K&N 57i Series Induction Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

I have now received the oil and air filters for all my cars- Range Rover Sport Supercharged, Jeep Grand Cherokee Limited, Jeep Rubicon, Mercedes Benz E430 and Porsche Cayenne S (only air filters for this one). I have used your products for a long time and am fully satisfied, so I keep the oil filters in stock for regular oil changes.

Firstly I want to say your filters are AMAZING! I will never have any car without them again. My first experience with K&N filters was in my 1976 El Camino back in high school, Flipped the air cleaner lid and BOOM cheap open element air cleaner haha.

But my review isn't about that it is about my 2004 Mercedes Benz CLK55 AMG cabrio. I joined the military a few years ago and this was my purchase to reward myself. When I first got it I was not averaging great MPG as you can expect from any 19 year old with a 400 HP car. However once I got used to it I drove it for maybe one month without the K&N's in. Once I put them in the car was a lot smoother with it's acceleration it wasn't on or off power it was a more linear pull. I realized my Mileage went up about 1.5 MPG. Well the real story is in the last few years I have put 50000 miles on my car with the K&N filter. Doing math today for fun assuming gas was 4.00 a gallon ( which it was never that cheap you guys have saved me around $1310 dollars NOT including the price of factory mercedes filters for 50K miles. AMAZING Product Great quality I reccomend them to ALL of my friends and every car in our family has one.

Hello,
I installed the KN air filter in my 1975 Mercedes Benz 280SE and I noticed a very positive improvement in horsepower and gasoline consumption.  I've always taken very good care of my 37 year old car and this air filter was like nitro for my car
Well done KN folks
