K&N style filters (oil/gauze) do nothing for low end performance and have been proven to filter poorly compared to a paper filter from my dirt bike experience. They do increase flow at top end but also allow more particulate through. Personally I would not purchase a used truck or motorcycle that had a K&N style filter used in it.Thorsenator said:Anyone have the K&N Filter system? Is it worth the $$'s?
Armada said:I wonder what is meant by "installed properly"? If you are using the factory air box, you will note that the air comes in from the bottom of the filter and goes UP through the filter and then out to the intake tube where it encounters the MAF sensor on its way to the intake manifold.
