Sorry, dude (mechano), but this test is no good. For a test (of any kind) to be useful it must be two things- valid and accurate. Valid means it measures what is intended to measure. Accurate means it is repeatable. This is not repeatable. Too many variables that cannot be controlled. Day to day changes in weather, temperature, relative humidity, polution, what ever was in the bed of the pickup 3 cars in front of him, different roads driven, different mile on tests, etc. The test was not conducted in a controlled environment. There is no way for it to be proven or even assumed that all conditions were consistent between tests. Also, there was no control group tested. It is, in reality, just a random test. The guy wasted his time.

Also, K&N’s actually flow better and filter better when they are a little dirty!
