        Totally happy with this reusable filter. Have had some K&N filters not fit correctly but this one is perfect. Not sure about the performance\mileage at this point but that's not really what I was worried about in a 4 cylinder 4 door sedan. It was about not throwing out something I could reuse.

          Big fan of K&N replacement air filters and they are designed to increase horsepower and acceleration while providing excellent filtration. K&N air filters saves you money on the long run and the same time, you don't have keep buying a new filter every 15,000 miles.All you have to do once it gets dirty, is to washed...let it air dry and it's ready to be used again...over and over. A must buy item, for any auto enthusiast.

                Comments about K&N Replacement Air Filter:

                I have been using K&N air filters since 1991. I have had them in 6 cars, 1 motorcycle and probably driven close to a million miles in that time. I have never once had a problem with these filters. They do give you a little better gas mileage and a little better performance but for me it's about cost. I tend to buy cars new (or near) and keep them until they just about die and over the life of a car it's much cheaper to start out with a K&N filter and keep it for life. The best tip I can give you came from my mechanic who told me DON'T throw away your old filter. When you clean and re-oil your K&N you will need it. Let the K&N sit for 2 days to dry and use your old one while it's drying. Now you don't have to worry about oil getting on any sensors and damaging them. (That one was for all the nay-sayers) ;-)

                    • Q:

                      My question is the factory air filter element has filtration thoughout the entire air filter,and the KandN air filtration element is not even three quarters the size does that not restrict air flow compaired to the factory air filter because there is less surface area on the KanN filter?

                        The K&N air filters are designed to have a higher airflow rating than manufacturer air filters.
