Mother-Daughter Racers Breaking Snowmobile World Records for That Girl Racing

The track is twisted, with jumps, sharp turns and hairpin curves. The snocross circuit is demanding on racers, allowing no room for distraction. There is no doubt that the mother-daughter relationship is also demanding and powerful. Tiina Duncanson is the mother, Kiersten Duncanson is the daughter. They are That Girl Racing and both are world record grass drag racers.

“My daughter and I were racing in a professional competition when her sled came up hard,” said Tiina. “For a moment I wondered if I should let off the throttle and go back to her, only for a moment.” Tiina decided to race. “It’s that competitive mother instinct, I finished the race and I won.” Kiersten was okay and would have been mad if Tiina stopped. Tiina also said she knew her husband Peter was right there.

These races test the maneuverability and acceleration of the machines, while putting the skill, agility and balance of racers to the test. The next snowmobile race for That Girl is the Canada-USA Championship at St.George de Beauce in Quebec. Some say this is where ice drags began. It is a split event over two days of racing with regular points. The challenge is American vs. Canadian. “I’ll drive my 800, with the K&N filter (RU-1480),” said Tiina. “If you can’t keep the pistons alive you can’t win and if I didn’t have my K&N filter there would be no way.”

Snowmobiles are sold with an air box and not an air filter. Extreme riders and racers remove the air box which leaves them with no protection. To compete, they put a filter on to aid in filtration. It’s necessary in grass drag racing to keep dust and grass strands out of the motor.

“In grass drag racing you have to have a filter,” said K&N Engineering Powersports Brand Manager Johnny Jump. “Without a filter all those grass particles and dust will get into the engine, scar the pistons and tear the motor apart.” As the sides of the skirts of the pistons get worn down from dust and contamination, it breaks down the seal the piston has within the cylinder, said Jump. “Less seal means less compression.”

Tiina said anybody who is anybody on the circuit runs a K&N. “I watched another brand, with a green filter collapse on the course,” she said. “The K&N filter keeps the dirt and snow out of my engine.”

Tiina is known as “That Girl” and Kiersten, 18, is known as “That Other Girl.” Tiina got into the grass drags around 1997. “My husband, Peter used to show antique sleds and that went hand-in-hand with the grass drags,” she said. “I wanted to race and he figured I'd be over it in no time, not so.” Now Peter Duncanson is in the racing business 24-7, said Tiina. Peter keeps the machines running and is the crew chief.

Kiersten began racing at the age of 12. Tiina taught her to drive and to pick lines on the track. “My daughter and I are like mirror images, “said Tiina. “Kiersten is number 721 and I’m 127.”

“Kiersten turned pro when she was 14-years-old,” said Tiina. “We pulled her out of the junior division and put her in the pro-division because she was winning everything.” It didn’t take Kiersten long to prove herself on the pro circuit. Kiersten broke Tiina’s world record three years ago, said Peter. “She did 5.2 seconds @ 93 MPH in the 500 open-modified.”

That Girl Racing uses K&N filter part RX-4140 on the 1000 and SN-2620 and SN-2510 in snocross, said Peter. RX-4140 is a K&N XStream filter, it works well in the 1000 because air can go into the sides and through the top of the filter and you also gain filtration.

“On the 1000 open-mud I have a three year world record,” said Tiina. “Every year I’d break it by dropping the notch a littler farther.”

That Girl Racing will have a new sled for the World Series in Sault Ste Marie, Ontario. “We’re always keeping up with the latest technology,” said Tiina. “It’s great to be a female driver with the fastest sled in the world!”

Racing Team Discovers K&N Oil Filters Reduce Maintenance Costs

Racing season begins for Wolfe Motorsports in the Bullring at the Las Vegas Motor Speedway in Nevada, and each one of its vehicles will have a K&N oil filter this February, said owner Matt Wolfe.

The divisional and national championships are open to drivers competing in the top class at each NASCAR Dodge Weekly Series track, including Late Model Stock Cars, Modifieds, Dirt Modifieds, Dirt Late Models, Late Model Sportsman, Super Late Models, Super Stocks and other styles of cars. Wolfe Motorsports tests February 25th and the season begins March 25th, according to Matt.

“We race all four of our cars 56 times a year,” said Matt Wolfe. “We have 2 Super Late Models, 1 Late Model and 1 Modified.” All have K&N oil filters, said Matt.

K&N Automotive Oil Filters

Wolfe Motorsports installed K&N oil filters (HP-5001) in place of what the company called “Brand X.” “We noticed after one race when we would normally change our oil, that we could go two races,” said Matt. “After two races we noticed that we still did not have to change our oil.” We asked the technical staff what was going on and they laughed because they already knew the capability of K&N filters and said we could go 4 to 5 races without changing our oil.

“We race with K&N oil filters and only K&N oil filters,” said Matt. “To top it off the oil filter is cheaper than ‘Brand X,’ and we don’t have to change our filters as often as we did before we switched to K&N.” It cut our maintenance budget by two-thirds, Matt said.

“Usually we smell the oil at the end of a race to see if it is okay,” said Wolfe. “We even had it sent out and tested to see if it was still good.” Matt Wolfe said they have really reduced oil changes with the K&N filter.

K&N Engineering’s premium Performance Gold Oil Filter has many features to satisfy the demands of racers such as drilled safety wire holes for racing, heavy duty construction and a sturdy one-inch wrench nut to make oil filter removal quick and easy.

“The safety wire is a nice feature,” said Matt. “We use it when we run a long race.”

Wolfe Motorsports won two Division championships two years in a row. “We won the Super Late Model Championship in 2004 and 2005,” said Matt. “We also placed 4th in the region among 12 race tracks and 180 competitors.”

Computer Case Manufacturer uses K&N Air Filters to Reduce Service Calls

K&N filters work extremely well in vehicles, but one southern California man discovered K&N’s proven technology also works extremely well in the computer industry.

Clean-Aire Computer Case with K&N Air Filter Keeps PC Components Clean in Dusty, Dirty Environments
Commerce Technologies LLC of Santa Ana, California is in the computer business. For years, employees downed servers and cleaned systems at companies where computers get dirty. “Computer dirt is an afterthought in my industry,” said Peter Maddox, managing member of Commerce Technologies. “When users see the pop-up line, ‘the computer has performed an illegal operation and will shut down,’ it’s usually not a hardware problem, it’s a dust problem.”

In order for a chip to remain cool air has to physically go across the top of the chip. A computer chip attracts dirt because of its magnetic field, said Maddox. “As more dirt builds up, the computer starts to heat up because the air is not moving.”

Maddox said he wanted to improve the way he worked and went on a search for the right filter. “HEPA filters are not reusable and depending on the size of the filter can cost up to $30.00 a month,” he said. “I tested one filter after another, from just about every store you can think of.” Maddox said they all failed and some filters he tested would actually pass small pebbles.

One day Maddox was in an automotive store. “I stumbled across a K&N filter, it was the right size and shape, a perfect 7 inch square, and it was reusable,” he said.

Maddox brought it home and tested with baby powder and a fan. This simulated a situation that could bring down a PC. The K&N filter worked despite the baby powder, said Maddox. “I didn’t have to look for filters anywhere else.”

With K&N’s multi layers of oiled cotton gauge, dirt is captured by tiny cotton fibers as it attempts to travel through a passageway. This area is designed to change and alter the direction of dirt particles. As a K&N filter is used its efficiency rating goes up. It’s true the filter gets better as it gets dirty.

The K&N filters work on computers in conjunction with Clean-Aire Computer Enclosures at several companies, said Maddox. “One of my clients is a greenhouse, and the dirt stays away from the computers.”

When I go into businesses people say, “Hey, I have those filters in my cars and are amazed how efficient K&N filters are on computers,” said Maddox.

“I put the K&N filter in my enclosures and so far the same filters have been running for 4 years at a sheet metal shop in Anaheim, California,” said Maddox. “I used to go in and clean the PCs every 6 weeks, but the designed enclosures with K&N filters brought about an immediate reduction in service calls, at least 40%.”

Maddox uses a black base in his enclosures to prove his point. “You should see my customers when I advise them not to clean the K&N filter,” he said. “I want them to wait until it is completely covered in dirt.”

“I also use the K&N cleaning kit to go with the filters,” said Maddox.

“I tell my customers about the K&N Million Mile Warranty,” said Maddox. “No PC will go a million miles but I’m just starting to get an idea of how long these filters will last. I haven’t had any complaints about the K&N filter in the Clean-Aire Computer Enclosures in 4 years.”

“The filter was the key, nothing matters but the filter when it comes to keeping a computer clean,” said Maddox. “K&N is it.”

K&N Engineering is a filter technology pioneer in automotive, motorcycle, and marine applications. In addition to washable/reusable high flow air filters, K&N offers several lines of high flow air intake systems and heavy duty performance oil filters.

K&N is proud to manufacture air filters for more than 55,000 applications, covering a fast majority of the vehicles on the road today. More than 600 employees research, develop and manufacture K&N products.  Go to to find products for your vehicle or to find a universal filter for just about anything else that needs clean air.

K&N’s New Typhoon Intake Produces 10 HP for the 2005 Pontiac GTO 6.0L

The 2005 Pontiac GTO's 6.0-liter V8 is a torque monster that can deliver a good performance package. Wind it up to the 6,500 redline and the dual exhaust belts out a high-pitched wail. If a Pontiac GTO pulls up next to you at a stop light, it deserves some respect. K&N Engineering now gives the GTO more of a boost under the hood, with a 69-Series Typhoon Intake Kit (69-7201TP).

K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction allowing more air to your engine. On K&N's in-house Dynojet dynamometer the Typhoon (Part Number 69-7201TP) produced gains of  10 HP. More air means more usable power and acceleration throughout the engine's RPM range. The K&N 69-Series Intake Kit for the 2005 Pontiac GTO consists of  a aerodynamically-designed filter that has a chrome top with the K&N logo stamp. It is 6 inches tall and has a base diameter of  7 1/2 inches. 

As with all K&N High-Flow Air Filters, the element included with the Typhoon Intake Kit for the GTO is washable and re-usable. K&N recommends cleaning the filter every 100,000 miles (depending on driving conditions).

The Typhoon's polished aluminum finish also looks great and the Short Ram configuration makes this kit easy to install.

K&N Engineering’s New Replacement Air Filter for the Chevy HHR is Available

K&N Engineering's lifetime replacement air filter (33-2339) for Chevrolet's 2006, 2007, 2008, 2009, 2010 and 2011 HHR crossover is ready to go for the new car with truck qualities.

K&N's Replacement Air Filter for 2006 to 2011 Chevy HHR
K&N's 33-2339 Replacement Air Filter for 2006-2011 Chevy HHR
Inspired by the 1949 Chevy Suburban, there are two engine packages available: 2.2-liter Ecotec four-cylinder (143 horsepower) in the LS and 1LT; and a 2.4-liter version with dual-overhead cams and variable-valve timing in the 2LT.

The K&N 33-2339 air filter fits the 2006 to 2011 Chevrolet HHR 2.2L L4 and HHR 2.4L L4 engines.

Unlike disposable filters, K&N Air Filters use a unique pleated design comprised of an oiled cotton fabric; sandwiched between two layers of epoxy-coated aluminum screen. The filter captures airborne dirt particles while allowing a high volume of air flow.  Particles cling to the outside of the filter and actually become part of the filtering media. K&N invented the concept of washable, reusable filters more than 35 years ago.

More air means more power and torque when you need it. The 33-2339 includes the famous K&N Million Mile Warranty.

Chevy Truck Hits Million Mile Mark with K&N Air Filter Saving Owner up to $1800

One million miles, one vehicle and one K&N air filter all add up to one remarkable milestone in the life of Carl Judice, 66, of New Iberia, Louisiana. His snow white hair and southern accent go together to make him a southern gentleman who owns what some would call an extraordinary pick-up truck.

A vehicle is only as good as the mechanics and the servicing provided by its owner and Carl knows how much difference a K&N filter made in his one million mile engine. “I have a ¾ ton Chevy 1998 pick-up truck with over one million miles,” said Carl Judice, a truck driver. “I’ve had 400 oil changes but only one K&N air filter.”

There are service records at the General Motors Dealership, Musson Patout Automotive, in New Iberia from the first day of Carl’s new truck purchase. The paperwork trail proves the one million mile accomplishment with one K&N air filter.

“Really and truly the K&N air filter kept the engine going,” he said. “It keeps the dirt out of the engine.” Carl said his one and only K&N air filter reduced maintenance on his Chevrolet C2500 HD pick-up. He told K&N he never had to go into the engine.

Carl knows engines.  He grew up on a farm and maintained his own equipment until he became a truck driver 10 years ago. Dwayne Judice e-mailed K&N Engineering about his father, he wrote, “When he changed careers, from sugar cane farmer to oilfield transportation his vast mechanical knowledge became an asset.” Dwayne also told K&N his dad’s visits to GM Goodwench Technicians have been few and far between.

According to Carl, he changed three starters, three alternators and brakes, plus all the regular maintenance on his one million mile pick-up. “Whenever I open the cover and change my oil I look at the air filter,” he said. “If it’s dirty, I take it out and clean it.”

Carl told K&N Engineering he cleaned his air filter 10 to 12 times during his one million mile odyssey. “I don’t have a specific length of time between cleaning,” Carl said. “Sometimes I drive on dusty roads and I have to change it more often,”

“The factory recommends change every 15,000 miles on an OEM filter,” said Bojack Walker, Service Manager at Musson Patout Automotive. “We put the numbers together and at a million miles plus Mr. Carl Judice would have had to change it 66 times at a cost of about $30.00 each. Carl saved around $1800.00 by using a K&N filter.”

“I would never put a paper filter on any of my vehicles as long as K&N makes these air filters,” said Carl. “When I’m passing somebody, I press on the gas I go, I still have the power.” Carl is still putting miles on his truck today with the same K&N air filter installed.

K&N 1955 Chevy Restoration Complete and Ready to Hit the Road

K&N 1955 Chevy just back from getting painted
K&N 1955 Chevy just back from getting painted.

K&N 1955 Chevy on display at SEMA in November 2005
K&N 1955 Chevy on display at SEMA in November 2005.
Our ‘55 Chevy 210 sat in the garage of K&N Engineering for years, just a shell of its former self, conjuring images of a ghostly past of Elvis Presley haircuts and poodle skirts.

We purchased it for $11,000 when it was 45 years old from a man in Hemet, California. The primer was nearly done on our Chevy’s body, the fenders and doors were painted red. It sat in our garage for 5 more years unchanged, but when the Chevy turned 50, there was a sudden urgency in the air. K&N had a plan to restore it for SEMA (The Specialty Equipment Market Association) 2005.

“We decided to do it sometime around the end of August,” said John Hudson, K&N shop supervisor, one of the key players in the restoration process. “The first thing we did was take it apart, next we had it sandblasted.” After that, it was time have the paint job done.
When that was finished we brought the ’55 Chevy back to K&N Engineering in Riverside, California, evoking a momentum that began a 20 day restoration process that took us into the wee hours of the morning, sometimes seven days a week.

”We only had 20 days before SEMA and restoring it became our day and night job,” said Brad Beltinck, K&N Special Projects Supervisor, another key player in the 55’ Chevy project. “We just put our heads together, got the parts, went to the next part, put it together and went to the next part.”

K&N decided to go with a stock look and just a hint of retro. The colors had to stand out, the way General Motors and its domestic rivals did when they dominated the auto market in North America back in the 50s. “Platinum & Sunset” were selected as the exterior colors. The bench seats of our ’55 Chevy are all original and were meticulously restored. It is a unique match to the exterior, tan morphed with a splash of orange. The carpet is grey.

K&N put in new windshields, but all the trim and seals around the new rollup windows are original. “It’s not from our Chevy, but they are Chevy parts from ’55 or ’56,” Beltinck said. The door trim is original, but the mirrors are after market parts.

“Our ‘55 Chevy frame is also an after-market part, a trend for the hot-rod industry, “said Hudson. “From there we added a set of 18- and 20-inch rims, which were custom designed for the car.”

The Flaming River three-spoke stainless steel tilt column steering wheel is in place along with the original dash. The only piece of aluminum surrounds the radio. The Panasonic CQ-C990IU radio is digital, designed to be seen and heard. “It has a screen that is programmable, we can run K&N video when the Chevy is sitting or running,” said Beltinck.

K&N engineers tried to stay away from aluminum billet pieces. “A lot of the hot roders use after market billet, “said Hudson. “We prefer stock and like to think of it as showroom stock, as if we bought the car in 1955.”

The light switches are also all original and the LoKar gas pedal is powder coated in black.

K&N worked hard to have our Chevy physically together for SEMA, it looked so together, there was an offer of $125,000 to buy our Chevy. By the way that was without the latest engine.

However, K&N could not part with its new baby.

Our Chevy will be fully equipped and make its debut in March 2006 at the Goodguys Rod and Custom Show in Pleasanton, California.

We have put a General Motors small crate motor from its high performance line. The 383 engine cranks out 425 HP. Our K&N engineers said it will go 100 plus MPH without a problem.

Our Chevy 210 has a K&N midget air box. A 4-cylinder sprint car box modified to fit on a ’55. We went from 4 holes to one on the bottom of the air filter. It’s supercharged and helps maintain the clean looking theme.

“I machined the K&N logo on the filter with a milling machine called the computer numeric control or CNC,” said Rick Daniel, a K&N Racing Development Engineer. “The idea just came to me in a vision and it came out pretty cool.”

After Pleasanton, in June 2006, our ’55 Chevy 210 will join the Hot Rod Power Tour in Florida. When we go on the road it will have an air conditioner and a complete replacement set of tires. What a car!

K&N ATV Air Filter for the Honda TRX 300/400/450 Provides Performance & Protection

ATV owners put their machines to work in a variety of ways and under a myriad of conditions. From herding cattle to dusty farm use, towing trailers and running through deep mud in the hills, K&N Engineering has developed an air filter designed to blow through most definitions of abuse.

K&N Engineering's HA-3098 performance air filter is designed for extended use in dirty off-road riding and also provides clean carburetion at sea level as well as high altitudes.

If you own a Honda TRX400 or TRX450 Foreman or Honda TRX300 Fourtrax, TRX450FE or TRX450FM Foreman you are in luck!
Replacement Air Filter for some Honda TRX300, TRX400 and TRX450 ATV's
K&N HA-3098 Replacement Air Filter for select Honda TRX300, TRX400 and TRX450 ATV's.
The K&N HA-3098 air filter like all K&N air filters are work horses. They typically provide longer service intervals and are designed to increase horsepower and acceleration.

Travis Horner, a K&N customer from Iowa wrote us, "I have installed the filter (K&N HA-3098) and have noticed a quicker throttle response and improved horsepower since adding this to my quad."

Calvin Crossland of Alberta, Canada also purchased an HA-3098. Crossland e-mailed K&N about the air filter, he wrote, "I have noticed a great deal of performance since I have added the filter. I have more bottom end power and top end."

K&N replacement air filters are washable and reusable.  The K&N HA-3098 lasts up to 50,000 miles before cleaning is required, depending on driving conditions. As a rule, no ATV jet changes are required with just a K&N filter element.

This filter is also covered by our K&N Racing and Off Road Limited Warranty. All K&N Universal Air Filters and K&N Air Filters sold for racing and off-road use are warranted against defective materials or workmanship for one year from date of purchase with no mileage limitation. This includes K&N Air Filters sold for ATV and motorcycle off-highway and/or dual-purpose use.

The HA-3098 will fit the following vehicles:

2003 HONDA TRX400FW FOREMAN 4X4. 395
2002 HONDA TRX400FW FOREMAN 4X4. 395
2001 HONDA TRX400FW FOREMAN 4X4. 395
