I recently purchased a K&N air filter for my 2001 Chevy venture; 3.4 liter engine. Since then there has been a very noticeable increase in acceleration, especially nice on interstate driving. The engine also idles much smoother then before. I don't think that my mileage is any better; marginally maybe; but even if it isn't the filter is worth every dollar I spent on it. The instructions were clear and easy to follow which made installation a breeze!!!!! Thanks for a great product!! Proud to have the K&N sticker on my back bumper.

I bought a K & N FIPK for my 1995 Chevy Camaro when I got the car in 1998. I installed the kit my self and it was very easy to do. I could literally hear whistling of the filter pulling in air. The performance improvement was noticeable right away. The gas mileage increase was excellent. The range I got from a full tank of gas before was about 240 miles. With the K & N Air filter and a Flow Master muffler I was getting 300 miles to the tank. I went from 16 mpg to 20 mpg. The best part was that I had the Camaro for 4+ years and only cleaned the filter twice. It more than paid for itself and cleaning it is easy.

I sold the Camaro and now have a 2002 Pontiac Aztek. I know, I know, it is ugly, but I like it and that is all that matters. Anyway, I am going tonight to pick up the K & N Filter for my new Aztek. I can't recommend these filters enough. Nothing else gives you as much bang for the buck.

I own the very first car I ever was a passenger in: a '66 Oldsmobile Delta 88, and recently purchased a K&N filter for it after I had the 425 under the hood partially rebuilt.  This is not the first K&N I have owned, and it will not be the last.  I have always been impressed with the money I have saved by buying these reusable filters, and have noticed a slight improvement in throttle response and fuel economy.

Both my 425 and I thank you for such a good product!

Now if you could make a K&N cabin filter for my '02 Pontiac Montana ...
