Got this filter as an additional one so I can rotate between two. One is in use while the other gets cleaned, dried, and oiled. Have never had an issue with this, or any K&N filter that I have and I would recommend this to anyone. Bought a filter wrap to go with this and I have to say, it puts a whole new look to the engine when opened. Simply amazing.

I have used K&N filters on my trucks for years. So much better than regular paper filters that have to be thrown away and then purchase a new one every six months.

I have used K&N in most of my cars since K&N became available. I truly believe in the K&N product, and stand by K&N filters 150%.
