Customer Feedback

I put in a K&N Filter in my 1999 Kia Sportage a year ago which now has 250,000 miles on it.  The increase in power and gas mileage was and still is amazing.  The air intake was resticted to about 1 1/2 before the air box and I drilled 5 holes at the bottom and rear of the air box which allowed much better air flow and I haven't had any problems with water even in the heaviest rains..  At a 1/4 million miles, the Sportage has better acceleration, gas mileage, and power than when it was new. Best investment I've ever made.  I also put them in my Toyota Tacoma, and Chevy S-10 with great results.  Do yourself a favor and buy one, you won't regret it.

I recently had to retire my 1990 Mazda Protege GT (1.8l, 4cyl) and bought a used 1993 Mazda 626ES with a 2.5l V6 (both with manual transmissions, but the 626 is a much bigger and much heavier car).  I was a bit concerned about the fuel consumption of the 2.5l having had a car with a smaller engine (27~30 mph city, 40+ mpg highway).  I bought the K&N filter to see if it could help out with squeezing a few more miles per gallon.  Presently it stands at about 25 mpg in mixed driving.  While it's early to tell, what I can tell you is that from the first time I turned over the engine, I knew that there was a difference.  

The filter in the car (when I bought it) was brand new.  I felt that the engine was a little slow on response when I pressed on the gas pedal, even when it was already revving.  I thought that this was normal as I hadn't had the car for very long.  With the K&N filter and without a doubt, the engine revs up much more freely.  It's amazing how getting more air into the engine literally breathes new life into it!  An of course, there is that little improvement in the sound of the engine as well.

Again, I'm not sure (yet) about any mileage increase, but will write back and repost after a few tanks have been used.  So far, very impressed!  The Zoom-Zoom is back!

I have been a fan of K&N air filters since the mid 90's.  The first filter I used was on my 87' Jeep Cherokee and it made a huge difference!  I immediately gained a 10% increase in gas mileage, faster throttle response, and a much smoother running engine.  The Straight 6 4.0 Liter engine is amazing to start with, but even better with a K&N!  I have installed half a dozen K&N filters on my friends' vehicles including a 97' GMC 1500 Truck, 98' Mazda 626, and my 01' Jeep Cherokee.  What a great product!!!
