I just recently sold my 1997 Ford Ranger 2.0 4cl manual that I had owned for 8 yrs. One of my first aftermarket purchases for that truck was a K&N factory replacement air filter. What a difference!! The truck actually had power after that filter was installed. Fuel mileage also went up considerably with a best of 26 MPG with an open bed. Also the truck had a rough idle with the stock filter that completely disappeared with the K&N. I put over 120,000 miles on the Ranger (a.k.a Blue) and only had to clean the filter twice. And I must say cleaning the filter was a lot easier than I expected.
Due to my satisifaction with the product I have purchased a K&N for my recently purchased 2007 Chrysler PT Cruiser. The PT has what I consider a dismal 22 mpg combined ( hey for a 4 banger I don't think that's great). I'm looking forward in seeing the increase in mpg with the K&N. That is if I can behave myself now and keep my foot out of it! I've already noticed an increase in acceleration, and a lot smoother idle. Also there was a slight lag in power when I passed cars with the AC on. That lag is no longer present and power production is smooth and uniterupted.

Awesome product, highly recommended.
Anyone thinking the cost of these filters is high, trust me when I say it is worth it. The cost of the filter is quickly recompensated in gas savings and filter replacements.

I've had great results using your FIPK kits. Installed this one on an '03 PT Cruiser GT 2.4 Turbo 230HP stock. Added this kit and noticed differance in acceleration as usual. This is the 4th vehicle I've installed an FIPK kit on, (1) '98 Dakota 5.2 v8 84,000 mi. before trade off to (2) '02 Dakota 4.7 V8 now has 206,000 and still going and my wife's '06 Chrysler 300c 5.7 Hemi and she noticed the differance the first time she drove it. These systems work great for performance and fuel economy when you can keep your foot out of the pedal ;-)

Well I have been running the K&N air filter on my 04 Dodge Neon and 05 Chrysler PT Cruiser convertible for about a year now.  I am VERY HAPPY I spent the money.  Respectively my gas mileage has been solid 30 and solid 25.  As for the Neon, I can't compare with old filter since I got the K&N within a month of the purchasing the Neon. But for my PT I am soooooo pleased since the only time I got above 21mpg before the K&N was on the highway.  Then it was usually 25-26.  Since K&N I get solid 25.  K&N is the BEST and I will never drive another vehicle without one.
