Customer Feedback

Back in May of 2006 I acquired a K&N air filter for my 1998 Chevrolet Malibu with a 3.1L engine. Due to the amount of driving I do (Sometimes as much as 650 Miles a week!) I was amazed at the gas mileage I was getting. Before the K&N, I was getting about 28-31 mpg's on the highway. I am now getting approx. 34 (if I keep my foot out off it.) The throttle response has also improved and as a volunteer firefighter, every second counts. Now I am patiently waiting for a K&N FIPK. Hope one comes soon 'cause I'll buy it. I STRONGLY recommend K&N to all my friends and co-workers. Thank you, K&N, for such an amazing product.

To the People of K & N,

Two weeks ago, I had the pleasure of meeting two gentlemen who build and work with Formula racing cars. Intrigued in their knowledge and expertise in auto mechanical systems, I asked them if there was anything I can do to increase the horsepower on my vehicles without expensive or extensive engine repairs or adjustments.  They both "highly" recommended K & N filters for my cars.  I went to a local auto parts store and found the same enthusiasm from the sales clerk and store manager who said they both have K & N filters on their cars.  I had to find out for myself after receiving these two endorsements and purchased my first filter on the spot.

I have a 2002 Chevrolet Malibu that I installed the air filter in one week ago.  I can say with confidence, there is a increase in my acceleration power.  I raved to my wife about the increased performance for the past week and purchased an air filter for her 1999 Honda Accord yesterday.  Just finished installing her filter and registering it online.

We haven't driven her car yet with the new filter installed, but I am sure we will both realize the improved performance.  Thank you for your research and development of products to enhance the performance of "everyday" cars.  I know that whatever cars I own in the future, they will have K & N filters installed in them.

Please keep us informed of other performance enhancing products for our cars.

I am averaging more then 5 miles per gallon more on my 2014 chevrolet silverado 5.3 liter. My wife thought I was crazy, until she drove it and saw the savings herself. I will never use another filter again. K & N air filter is the best.
