Comments about K&N Replacement Air Filter:

If you are searching for a replacement air filter, this is it! I have replaced every airfilter in every vehicle I have with a K&N replacement. You cannot beat the performance, the warranty, and the simple fact that you can reuse this filter over and over. Don't forget to pickup a cleaning/recharging kit so when it comes time to clean and reoil the filter you can do so. Also... keep your old airfilter in the K&N box for when you have to go and clean the K&N. You have to wait until the filter is completely dry before you reoil it. Leaving your vehicle incapacitated for a while. BUT if you have your old filter you can just pop that back in for a few if you need to use your car in the meantime!
