INSTALL YOUR NEW INTAKE AT HOME IN LESS THAN AN HOUR

INCLUDES STEP-BY-STEP INSTRUCTIONS

Even if you aren’t a seasoned mechanic, you can still install your new intake in your home garage. K&N intake systems are engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 60 minutes or less, and requires only simple hand tools.


Detailed, step-by-step instructions are included in your kit, and installation instructional videos are available on our website and YouTube channel for many applications. View the product page for the most up-to-date vehicle compatibility information.

INCLUDES AN OVERSIZED OILED COTTON FILTER

An oiled High-Flow Air Filter™ (included in the kit) helps increase airflow to your engine—while simultaneously providing exceptional protection from contaminants. The oversized filter shape allows for up to 100,000 miles between cleanings (under normal highway driving conditions). When it does need to be cleaned, you can use K&N cleaning products to quickly and easily restore your filter’s performance. Each intake and filter is designed to last for the life of your vehicle.


When K&N engineers design a diesel replacement or intake air filter, much consideration is put into improving diesel performance without sacrificing engine protection. A K&N diesel air filter is typically built to higher specifications than K&N's standard automotive air filters, and feature extra deep pleats for a larger surface area and additional layers of cotton to achieve high levels of filtration efficiency. K&N performs filtration efficiency testing following the internationally recognized ISO 5011 protocol to guarantee that a K&N diesel air filter will provide high airflow without sacrificing engine protection.

INTAKE TUBE DESIGNED JUST FOR 2500/3500 MODELS

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. These systems feature precision-engineered intake tubes designed to keep airflow to the throttle body smooth and oxygen-dense.

IMPROVES ENGINE SOUND

Factory intake systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and muffle engine noise—unlike K&N® intake systems, which are designed to give your engine a more satisfying growl on acceleration, but return to quiet once at speed.

PROTECTED BY K&N’S WARRANTY

Each intake system comes with a 10-Year/Million Mile Limited Warranty***.

THE CUMMINS DIESEL ENGINE: A BEAST SINCE 1989

Cummins Inc. has been a major player in engine manufacturing since it was founded in 1919 by Clessie Lyle Cummins. The Cummins Engine Company focused on developing the engine patented by Rudolf Diesel years earlier. With decades of experience developing and building diesel engines, it was no accident that Dodge began offering the Cummins Diesel-powered Ram pickup in 1989. The Cummins Diesel engine-powered first-generation Dodge Ram soon became a viable alternative to large gasoline-powered V8 engines. In fact, the Dodge Ram diesel was beating its competition from General Motors and Ford by being the only member of the big three to offer a turbo diesel engine; in addition, the 5.9L Cummins 6BT 12-valve diesel was direct-injected and didn't rely on glow plugs for cold starting.


Despite the Cummins Diesel engine, the first generation Dodge Ram, merely a face-lifted carryover of the Dodge D-Series which had been around since 1972, sold poorly compared to its counterparts from Ford and GM—until 1994, when Dodge introduced the second-generation Dodge Ram pickup. The fully redesigned 1994 Dodge Ram 1500 immediately became a sales success. Dodge carried over the 5.9L Cummins 6BT 12-valve diesel engine as an option for second-generation Ram 2500 & 3500 models. Although the Cummins 6BT 12-valve 5.9L L6 Diesel outperformed the 5.9-liter LA/Magnum V8 engines found in the first-gen Ram, Dodge introduced the 8.0L Magnum V10 engine as an option for 1994. The 8.0L Magnum V10, basically a cast-iron version of a Dodge Viper engine, was the most powerful gasoline-burning pickup truck engine of the time.

Get More Power from Your Diesel with a K&N Intake

All engines are essentially a giant air pump—and anything that can be done to eliminate restrictions on the intake and/or the exhaust will likely improve performance, but we often see the most dramatic gains in modern diesel engines. Large displacements and variable vane turbos demand incredible amounts of air in order to run at peak efficiency. A K&N intake will nearly eliminate intake tract restriction and enable an engine to breathe easier, resulting in more power. Best of all, a quality aftermarket diesel air intake system offers simple bolt-on installation and an incredible bang for the buck.


1994-2002 Dodge/RAM 2500/3500 Intakes

Second-generation 1994-2002 Dodge Ram 2500 & 3500 featuring the Cummins 6BT 12-valve 5.9L L6 diesel, or the mid-1998 and later Cummins ISB 24-valve 5.9L L6 diesel engine, can easily bolt on more horsepower and torque with the 57-1525. This system replaces the factory accordion hose ducting with a performance engineered roto-molded high-density polyethylene (HDPE) air intake tube, and a high-flow washable and reusable K&N air filter. This kit also includes an application-specific air filter heat shield to help deflect the high under-hood temperatures associated with diesel engines away from incoming airflow. Installing the 57-1525 resulted in an estimated additional 9.17 horsepower and 18.79 lb-ft of torque at 2,560 RPM on an otherwise stock 1995 Dodge Ram 2500 5.9L.

"Great kit. Been in use on my Dodge Cummins truck for 10+ years." - Eric from Arizona

2003-2009 Dodge/RAM 2500/3500 Intakes

Dodge rolled out the third-generation Ram 1500 pickup truck in 2002, with the 2500 & 3500 Ram trucks debuting a year later. With its proven reliability, Dodge carried over the Cummins ISB 24-valve 5.9L L6 Diesel engine into the new trucks. In January 2007, the 6.7L L6 Cummins was introduced, and had both Chevy and Ford beat. K&N offers a selection of intakes for owners of 2003-2007 Dodge Ram 2500 & 3500 5.9L Cummins diesels, as well as 2007-2009 Dodge Ram 2500 & 3500 6.7L diesels.

2003-2007 2500 & 3500 5.9L

2003-2007 Dodge Ram 2500 & 3500 5.9L Cummins diesel truck owners can choose from either a roto-molded HDPE air intake system (57-1532), or one of K&N's newer diesel air intake system styles; the Blackhawk 71-1532. Instead of an HDPE tube and traditional K&N oiled-cotton air filter, a Blackhawk Induction System uses a mandrel-bent aluminum intake tube and a non-oiled synthetic media air filter. While both diesel intake systems offer a performance boost, K&N's roto-molded air intake tubes and traditional cotton air filters tend to perform slightly better in terms of horsepower gains. In this case, the 57-1532 provided an estimated additional 10.96 horsepower and 20.17 lb-ft of torque when tested on a 2003 Dodge Ram 2500 5.9L Turbo Diesel, while the 71-1532 provided an estimated 8.09 HP and 14.27 lb-ft of torque when tested on a 2006 Dodge Ram 2500 5.9L diesel.

"This product was exactly as advertised and gave my truck a very noticeable horsepower increase. Very impressed with results for the money." - Andy from Illinois

2007-2009 2500 & 3500 6.7L

2007-2009 Dodge Ram 2500 & 3500 6.7L Cummins diesel truck owners have a nearly identical choice between K&N diesel air intake system styles. The 57-1557 features a roto-molded air intake tube with an oiled-cotton K&N air filter, and provided a massive estimated additional gain of 20.63 horsepower and 43.35 lb-ft of torque to the wheels of an otherwise stock 2007 Dodge Ram 3500 6.7L CUMMINS. Under testing, the K&N Blackhawk Induction System 71-1557 provided an estimated increase of 9.29 horsepower and 19.11 lb-ft of torque.

"Truck runs smoother than it ever has and starts easier. Increase in fuel miles per gallon maybe by 10 to 20 percent. It pulls my trailer up hills without shifting down. It would be very hard to go back to original equipment. Thank you K&N." - Donald from Wyoming

2010-2012 Dodge/RAM 2500/3500 Intakes

2010 ushered in a new generation of heavy-duty Ram 2500 & 3500 pickups, as well as a restructuring of the Chrysler Corporation, officially FCA US LLC. Now owned by holding company Fiat Chrysler Automobiles, Ram Trucks became its own brand that no longer fell under the Dodge umbrella. While the 6.7L L6 Cummins diesel engine has been carried along since its introduction in 2007, both the fourth-gen Ram Truck and its Cummins diesel engine have undergone enough changes to necessitate different intake systems for 2010-2012 Ram 2500/3500 Cummins powered pickups and 2013-2016 Ram 2500/3500 Cummins diesel trucks. Much of these changes revolve around increasingly tighter emissions regulations, more stringent electronic engine controls, and sensitivity to inlet air temperatures.

2010-2012 RAM 2500/3500 6.7L

2010-2012 RAM 2500/3500 Cummins 6.7L diesel powered pickup owners have a choice between a roto-molded HDPE system (63-1562), and a K&N Blackhawk Induction System system (71-1562). K&N engineered a large, free-flowing covered air filter box specifically for these trucks. The K&N roto-molded HDPE diesel air intake system incorporates a cold air intake snorkel to help draw in cooler air with an additional air source. (The 57-1562 is the version legal for sale in California). The result is an estimated additional 8.2 horsepower and 14.76 lb-ft of torque on a 2011 Dodge Ram 2500 6.7L Turbo Diesel. While the 71-1562 air intake system does not include a cold air intake snorkel, the performance enhancements are very similar. When installed on a 2012 Dodge Ram 2500 6.7L turbo diesel, the Blackhawk system provided an estimated additional 7.15 horsepower and 18.58 lb-ft of torque to the wheels.

"This intake was easy to install and works great. I have a 2012 Dodge 3500 dually diesel and pull a 37.5 foot fifth wheel. We've put on over 6000 miles since installing the intake." - Ed from Arizona

2013-2018 Dodge/RAM 2500/3500 6.7L Intakes

Keeping with the trend of increasingly tighter emissions regulations, more stringent electronic engine controls, and sensitivity to inlet air temperatures, Ram Trucks engineers had to get creative with the 2013 and later Ram Trucks 2500 and 3500 Cummins 6.7L diesel pickups. Ram Trucks engineers developed a new diesel air filter box technology that they call "Ram Active Air". The Ram Active Air box is a dual-inlet type diesel air filter box with the ability to vary the source of incoming air. In normal driving conditions, air is drawn from a protected source under the hood. As under-hood temperatures rise, the Ram Active Air filter box switches to a system drawing air from directly behind the truck's front grille. Ram developed this system to combat power loss in hot, dry, up-hill conditions when temperatures under the hood have been shown to climb to extreme levels.


K&N performed extensive testing, and it was apparent that the 2013-2018 Ram 2500 and Ram 3500 6.7-liter Cummins diesel-equipped trucks performed better by retaining the stock Ram Active Air filter box. As a result, the K&N intake system 63-1568 for 2013-2018 Ram 2500 and Ram 3500 6.7-liter Cummins diesel trucks replaces the disposable factory air filter with a K&N high-flow diesel air filter, and replaces the factory air intake ducting with a new roto-molded air intake tube, but leaves the stock air box.


On the dyno, the K&N 2013-2018 Ram 2500 and Ram 3500 6.7-liter Cummins diesel air intake produced an estimated additional 14.65 horsepower at 2500 rpm and a substantial 23.86 pound-feet of torque increase at 2122 rpm over the factory system when installed on an otherwise stock 2013 Ram 2500 6.7L Turbo Diesel. (The 57-1568 is the version of this kit that is legal for sale in California).
