For more than 30 years, K&N Filters have been the choice in engine filtration. The K&N filter delivers virtually unrestricted flow letting your engine run stronger, cleaner and with greater fuel efficiency.

The secret of the K&N filter is its filter medium. Four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This proven design stops dirt, dust and other harmful particles like no other filter, all while clean, power-enhancing air flows freely to your engine.

Just give it a simple cleaning every 50,000 miles and your K&N filter will last for the life of your vehicle. With no costly changes and services, your K&N filter will save you money. And, you'll be helping the environment by reducing the number of disposable air filters that end up in landfills.

Get increased power and acceleration, better fuel economy from a filter that lasts for 1,000,000 miles-get a K&N.

Merceds C240 K&N filters

"The Mercedes C240 engine has two air filters, and after installing the new K&N, the engine seems to run smoother and more aggressively. Installation took a little bit of figuring out, as you must remove the entire engive cover, where the filters are located, and then you need torx bits to undo, which I would suspect the average person would not have in their tool box. Total install time was about 15 minutes, which included cleaning the engine cover and vacuuming out the cold air intake tubes of debris. This is my forth purchase of K&N filters, and I beleive they really help the performance and MPG on the cars. Caroll in Maryland"

"I have a Toyota Prius. The 1.5l gas engine needed a little boost for longer hills and other acceleration situations. I replaced the original air filter with a K&N and have noticed improved performance when I need it most. I haven't used the filter long enough to calculate any fuel savings. I'm just pleased with the improved performance."

"I recently purchased a K&N filter from AnythingAuto for my wife's car.I got a great price and free,fast shipping from AnythingAuto but I'm really dissapointed in K&N's manufacturing quality.The adhesive around the edge that holds the rubber outer seal to the filter is poorly applied (see photo)and extends 10%to15% onto the filter area. I called K&N and they promptly sent me 2 replacements (one by accident)They were even worse. I ended up trying to pick the best of the three(see photo) and sent the others back. I've always used K%N in the past but now I'm not so sure I'll use K&N again."

"I've installed K&N air filters in my last four vehicles. Most recent application is a 2006 Jeep Liberty Ltd 3.7L V6. Primary intent this time around was to improve gas mileage (avg ~16.5 mpg around town). Still a little too early to tell, but it looks like ~1 mpg improvement with the K&N filter. Also have one in my 2.7L V6 Chrysler, and had one in my 99 Dodge Durango 5.2L V8, and 97 3.5L V6 Intrepid Sport. Improved throttle response is immediately noticeable in the Jeep and Chrysler. As you can tell from this review, K&N offers a wide range of applications for their products. And prices and selection at AutoAnything meet or beat local brick and mortar outlets. K&N is an inexpensive way to improve performance, right out of the box."

"Had heard of K & N for high performance motors. Decided to try on 97 BMW 540 and 2000 Mercedes S430. Both have 60K to 70 K Performance - speed of acceleration especially at low end RPMs is stronger. Have not tried high speed or RPMs as don't drive that way. BMW is quicker, but lighter car with nearly same motor size as heavier Mercedes. Best suprise is improved gas milage. Just under 3 miles/gallon on high way. With high gas prices - esp premium nice bonus. Will buy again, but sooner in cars life. lrk"

K&N Filter As Advertised

"I purchased a K&N air filter for my 1992 Honda Civic VX to replace the standard disposable filter (the VX was Honda's fuel efficient version of the Civic). I did not want to throw away any more filters, which will just end up in landfills. In addition, information I had gleaned from various "fuel economy" websites indicated that K&N's claims of increased mpg and power were true. After installing the filter, I did notice that the engine ran better, with a noticeable increase in power (the VX is tuned for fuel economy, and only gets 92 hp). My first gas fill up after installing the filter produced nearly 50 mpg-the best fuel economy I have measured in the 12 years I have owned the car. The previous best was 47 mpg. In summary, I do believe it worthwhile to replace the old paper air filter with a K&N; they are expensive ($40.95 in my case), but with the price of gas so high, the return in better fuel economy and the elimination of disposable filters will make up for that in short order."
