I always suspected that oiled filters were a gimmick. Reminds me of an article on the web in the late 90's that tested oil filters. Fram came out on the bottom of every test. The author / guy that paid for the test was sued by Fram ( who buy the way is owned by Schucks / Checker / Orileys etc) and forced by court order to remove the site from the internet. |

| There are many fram oil filter tests on the web yet. Fram always fails. Their more expensive line does compare to everyone elses regular line though. |

| I thought Travis did this test himself years ago and found out the same thing. |

I did. I tested the intake restriction of a stock paper filter and then emailed k&n and asked them how they could possibly do better. They said they couldn't. Their claim is that the k&n will flow better than a paper filter when you dump them both with the same amount of dirt. But why would you have a dirty filter? I'll never own one.
Good find though. _________________ E30
