Amazing engineering team and quality control! I've consulted many top manufacturing companies over the years in [brand],etc. Most company's 3-5 year vision is to be where you have already gone when it comes to customer service, quality, reliability and repeatability. You guys are leaps ahead of others in the manufacturing industry and I must say I'm extremely impressed with your entire team. The instructions were spot on and everything fit without much force at all. Your commitment to quality is superb but most importantly it is very evident the dedication to teamwork at K&N and it certainly shows in the end product. I'll definitely recommend you in the future. Thanks! oh yeah....the increase in HP for my 2012 Super Bee is phenomenal!

I have been using your RU-2590 universal filter on a 2000 Ford F-350 with the 7.3L diesel for many years. It seemed small for the application but it has worked fine. I am getting over 20 MPG (with other mods. also)so it's size has not restricted air flow. Diesel filters do require much more frequent cleaning than advertised - in my experience every 3,000 miles or monthly, especially if I have driven through rain. The rain washes the oil (and dirt) from the filter right into the intake and the turbocharger. I have been able to minimize this somewhat by using drychargers for the last 3 or 4 years. They do stop fines from entering into the filter element somewhat. During a recent replacement of glow plugs and a turbo rebuild at 370,649 miles, no wear was apparent within the turbocharger. I have used a 1 micron bypass filter and [brand] synthetic additive (2 oz./QT of oil every 30,000 miles) since approximately 11,000 miles so this has apparently contributed to the low or minimal wear (the magnetic drain plug is almost clean at oil changes). The only other thing I have noticed is that after 2+ years or 20 or so filter cleanings the rubber flange of the filters shrink a bit, become harder and will no longer fit on the 4 intake. I think I read K & N recommends +/- 25 cleanings before replacement anyway though.

I buy K&N filters for all my vehicles. Just bought the pickup. A new filter was the first purchase for it.Your web site was easy and shipment was prompt, and saved some cash over part store prices.

It should be noted that unlike the OEM filter from Toyota, the K&N does not include the drain cap o-ring or drain adapter. The o-ring used to be part of the filter assembly, but K&N must have decided it does not need to be replaced.

The filter represents good quality construction. Throttle response is noticeably improved on my supercharged 3800 engine. Initially the gas mileage was decreased. The computer system required a couple thousand miles and over a month to adjust and regain the gas mileage.

I highly recommend this item to help keep the off-road riding micro particals from possibly entering the engine. Installed on an arctic cat 400 4x4, it also helps extend cleaning periods to the filter!

Installing this filter dramatically improved the throttle response over the factory air filter. Installed on a 2006 arctic cat 400 4x4. I also purchased the dry filter cover to help keep out the small micro stuff for off-road use, which was highly recommended by a friend that is a atv mechanic!

It also gets rid of that tooty frooty sound tube. I can hear the exhaust a little better without the interference of the sound tube noise. Also, I do not want to put a tune on my motor, unlike some other cold air intakes, this intake will work without a tune.

Works great easy to install took less than 45 mins. I would give it a 10+

Easy to install, took about 45 min to install in 28 deg weather. My advice is to watch the install video to be on the safe side, helped a lot. Love the extra power, MPG's and it also gave me 4 more mph on my governed truck. Now I top out at 102 merging onto a highway is so much easier now.

I have been completely satisfied with the K&N product. When and where they are available I put them on every motor vehicle I get from Quads to Cars and Trucks. My last purchase was for a kid's Coolster quad (product of China). It made a huge difference in the performance in the heavy dust areas of the Southwest including the California Dunes.

Just what I needed to fit a 3-1/2 inch intake pipe with the adapters included with the filter. Fits my 2009 Dodge Charger SXT 3.5L as a short ram intake, but I plan on taking out the air silencer/resonator behind the front bumper and running the pipe down the hole and connecting the filter behind the bumper for true cold air intake from the lowest location.

Price on K&N webstore was very good. Shipping was quick. Correct filter was sent and product fit perfectly.

Perfect fit. Car seems more responsive, considering it is a turbo with a small intake and the stock filter looks restrictive. One advantage is this car requires a regular filter change yearly, and this will save me quite a bit of money in the long-run. Had one on my Nissan Maxima that ran 180,000 miles with no problem at all.

Excellent fit and definite HP gain when combined with custom tune. Took only an hour to install and was worth every penny. Looks amazing under the hood. Thanks K&N for listening to the consumer and making an all black intake system.

Product arrived on time. Looks different from original equipment. But fit into space provided and is working so far without problems. I suggest that you add an instruction sheet for those who have never used this type of filter.

Great performance, easy to clean and never have to buy another filter for this car of mine and saves me $30-$40 a year from not having to buy another filter.

I love these filters, this was the third one I have purchased, now all my vehicles are K&N equipped. I will never buy any other!

I expect that the oil filter is as good as K&N claims. I use a synthetic oil blend in my 2004 Kia Optima and appreciate that this oil filter is superior to other filters for synthetic oil.

Acceleration is noticeably improved. This alone gives me great satisfaction. I have not yet checked for a change in miles-per-gallon. Even if that were unchanged, the smoother acceleration with its quicker response from the gas pedal is wonderful.

Not sure there is any benefit to me. Makes a lot more noise and can't tell it has helped power or fuel mileage.

This is a great product and made a great difference in the performance of my F150. I used the step by step instructions online and had no problems. Also K&N should put an O Ring in the kit for the intake manifold throat for the throttle body. Reason why, the new K&N throttle body adapter isn't flat on the bottom and has seems where it was molded from factory, I had to resurface the bottom of the adapter so it would make a good seal.

Installed this on a 2005 Dodge Durango with the Hemi a year after buying the vehicle new. (has been on the Durango now for over 7 years). First thing you notice when removing the OEM air intake is all the extra sound dampner boxes and restrictive passages. The K&N is a large near-straight tube taking air directly to the throttle body. Has a nice large filter. Kind of a pain to get it off to clean due to being squeezed into a tight space but do-able. Once installed and I started up the Hemi it rev'ed up super high due to all the restriction being taken away (what it was use to). I then took it for a drive and it was night and day improvement in response and extra power. Took a week or so of driving and the computer adjusted and optimized to the new intake. Saw a tiny improvement in MPGs. The power & sound is awesome. When you get on it it really growls. If you drive conservatively it is near unnoticeable. Have had no issues with it over the years and filter has held up great. I would get it for any Hemi vehicle I own in the future.

These filters fit 76-79 Suzuki GS750,s 79 GS850's, 78-79 GS1000's, as well as the big Kawasaki four cylinders from the 1970's that use the same rack spacing with VM26 Mikuni carbs (Z1/Z900/KZ900, KZ1000, probably KZ750). I will never run pods, and always search out a K&N dual carb flange universal filter for better rideability and consistency in the fuel mixtures between the inner and outer carbs.

I just had the performance chip installed on my 2003 H2 Hummer where I'm saving a lot of gas, now I just installed the 57-3037. I'm just worried about the fan almost touching the intake arm. It's a tight fit the space between the fan and the intake is approx. 1 in.

The K&N Filter Service Kit arrived rapidly after ordering it, and it did a great job cleaning my filter. Now the filter is as good as new again!

Just arrived so I will see what it gives. Also the price here is $85.00 plus. I bought at Amazons for $39.99..Go figure. Need I say more. I gave it 4 stars for reusable filter, that is worth a lot. I really don't think it's going to enhance performance at all.

This was a perfect fit to the stock filter for my 2013 Accord Ex-L. I definitely noticed a boost in performance when I changed to the K&N filter, though I'll admit the stock filter was in need of replacement (after only 10 months, 40k miles).
