      Comments about K&N Replacement Air Filter:

      I have a 2010 Lexus GS350 that used to average 24 miles per gallon on stock filter from Toyota/Lexus. After installing the K&N filter and using for the past 8 months, I'm averaging 20-22 miles per gallon... Not pleased. I know most people swear by K&N filters and I've installed them in every car I've owned for the past 14 years but I'm not sure if I should go back to standard filter and see if mpg goes up on this vehicle?

      Comments about K&N Replacement Air Filter:

      I have 5 vehicles and have K&N Air Filters in all. 50,000 miles without cleaning and then the cleaning takes just a few minutes. My truck has over 100K miles and I'm still using the same filter - 900K miles left on the filter. Improved gas mileage and a little more umph in the "get up and go."

            Comments about K&N Replacement Air Filter:

            There are criticisms that the K&N air filter oil clogs the intake system. I've used these for years with no issues. Must be they put too much oil on the filter when they recharge it. If you keep the vehicle long enough, the filter pays for itself and beyond.
