OC, just by replacing your oem paper filter with a K&N will give you no gain to speak of. The big advantage of the K&N is that it will last forever but needs to be cleaned every so often. They make a cleaning and re-oiling kit too. Make sure not to apply too much oil. You would be better off to invest in a twin CAI system. Even these dont add a lot of gain but improves the looks and sound. They also come with conical shaped re-useable filters.
