Although the numbers do show a gain thrughout the RPM band, i couldn't feel any difference coming back home at WOT.
That being said, the engine "seems" to flow more fluently (especialy during downshifts).
Question for the techs folks: could the K&N oil affect the maf sensors and therefore changing the air/fuel ratio??? The filters were "out of the box"...

Awesome job on doing that test. 4 runs on each should leave no doubt that the filters do improve performance.

Just out of curiosity, how many miles or how dirty were the stock air filters used in this test? I assume you got the K&Ns brand new?

Drisko,
Good question, the stock filters were actually in good shape (besides a couple of bugs....). And yes, the K&N's were out of the box brand new!
ps. After 9k they still run fine and no issues with MAF...
