Ordered two both shipped quickly both fit. I could tell the increase in air flow in my truck, I have not had a chance to drive the other vehicle, but my wife said she felt no difference.

slight additional growl from engine is nice.............NOT objectionable...........extended life of filter is a long term investment vs the routine change of high priced mfg parts.

After installing the K&N air filter in my range rover I immediately saw improved torque and can actually feel that the engine is freer breathing. Have not noticed any appreciable gain in mileage yet, but it's only been a week and all city driving

I am a fan of K&N filters. This filter helped me get about 10% better mileage so far (after about a months use). I also notice a slight increase in throttle response, which is common with high flow air filters. Highly recommended.

Well I heard they help with gas mileage compared to the standard air filters. Like the fact that they are reuseable and think that alone is a plus, especially for my vehicle which requires two and uses premium gas and doesn't get the best mile per gallon ratio. Haven't had them long enough to know but I hope they help out, especially with rising gas prices. Look foward to see if they come through and meet my expectations.
