I have been using K&N filters for years on various vehicles and have never been disappointed. This particular kind of filter is not easy to find and I was very happy to find one available with the usual K&N high quality.

Picture makes it look like the only blue air filter available, but it just the angle the picture was taken. Returning. Would not have any other problem otherwise.
beside how K&N filters work they look cool also I have K&N on all my vehicles
