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...
