Does what is says.
Randall Graff, Grantsville, Utah
I have been using K&N Filters for well over a decade. The first thing I do with a new car is replace the air filter with a K&N before the first oil change. I have K&N air filers with over 125,000 miles on them, and they look like new after I clean and oil them. This purchase replaced the manufacturers air filter on my newest purchase and my wife noticed an immediate improvement in power and mileage. The filter arrived on my doorstep on the date as promised by K&N, and fit perfectly as always. Plus, this car is not an easy one to get a filter for locally, so a simple order on the K&N website and it arrived promptly. I plan to put well over 100,000 miles on this filter with a 10 year minimum life span. What I like most is when the mechanics lift my hood and see that K&N sticker on my air filter casing, you can tell they hate it because they cannot sell me an overpriced paper filter.

I use this filter in my car. Maintains a low engine temperature, fuel consumption improves and increases the power. Very good. Recommend it to everyone.
