Below are a few of the K&N product reviews that we have found from some K&N brand users:

"Right after I put the filter in I could feel a difference. The car had alot more pickup and I could here more air racing into the engine."

"Since installing the K & N air filter in my 2000 dodge Stratus I made a round trip of 3000 miles. Mileage increased by 1.8 mpg! Works great. Performance also improved with better accelleration from my little 2.0L I look forward to checking mileage and performance on my 1990 Chev PK soon and expect a boost in both."

"Was really impressed with my honda accord's filter, made a noticable difference in performance. Our Hyundai Elantra the difference was almost non-noticable. Pretty easy to use, either way a great money saver over time."

"Ive been driving for over 20 years and never used any filter beyond what I could pick up at a WalMart. Big mistake! My K&N will definately save me money in replavement filters, more then that, Im getting an average of 1.5mpg more. In these times of high gas prices, V8s need all the help they can get."
