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.

Bought a 2004 Hyundai Accent base factory. Bought the car used so it wasn't taken care of. Replaced all the plugs, wires, and fuel filter and jumped gas mileage from 19 to 24. After replacing the air filter with a K & N Filter gas mileage went to 32 MPG !! Changed the oil with synthetic with a K & N oil filter and got 37 MPG next tank !

K & N Rocks !!

Have installed K & N air filters on every vehicle ranging from the Hyundai, a 95 Camaro, 2003 Chevrolet Silverado and now a 97 Dodge Avenger. Waiting for the filter on the Avenger to come in, but know it will give performance and gas mileage that is unbelievable.

Found multiple people at auto part stores buying filters before - and told them the advantages of buying a  K & N performance filter, and it changed their mind from the $ 6 paper junk filter.

Keep up the great work K & N, love your products !!

need to study exhaust systems...that would rock to make a K & N Muffler !

I own a 1992 Oldsmobile Cutlass Ciera with the 3300 V-6 Engine. I noticed it still had a old air filter in it and ran it awhile and got about 315 miles to a tank of gas. My husband is a great fan of your filters so I got a air filter for the car and noticed the performance increase right away, the mileage went from 315 to 350 miles to a tank of gas. I love this air filter. I kept the old air filter to use in car when cleaning this air filter. My husband pulls garden tractors and uses 4 K&N Air Filters on them. He has ran those filters for over 13 years on the tractors. Thank You for great products.

Best of Luck,
