I use to run the K&N also. Then I had the opportunity to see a demonstration with a dinno. They ran it with a paper filter then with the K&N. The HP went down using the K&N. After seeing that I went back to the paper filter.
That demo was run using a Ford but I'm sure it wouldn't make any difference what they demoed with.
