Been using K&N products for many years. Back in the 90's I drove dirt race cars and used only K&N. When I bought this truck new in 97 I put a K&N filter in it. It works great, the only reason I had to replace it was because it got damaged working on the engine.

I have used this filter since 1995 and only in 2016 have I had to replace it.
