Excellent after market application. Simple steps to recharge filter. Treating your vehicle with this product puts you in charge of its care and feeding. Why trust some knucklehead with an inferior paper filter that may or may not fit? It's your machine...give it the best!

So far so good. But just have had in for a couple of weeks. Again, so far I like what I have seen.
Ray Jones, Weatherford, Texas
I received the air filter timely. It installed easily and is performing very well.
