I found a credible third party test on filters. (BTW Bobistheoilguy.com is a great site for all things PM related) The AC Delco filter is 99.9% in the test below. The K&N, 96.8%. Sounds great huh? That's only 3% difference right? Now pay attention to the dirt passed. The AC Delco, 0.4g. K&N 6.0g. So that K&N let 15 times more dirt into the engine.

It's everyone's vehicles, do what you like. We're not talking about powerhouses when it comes to the 6.2/6.5 family of engines. So anything you do to pick up power puts you in a better place. Just wanted some of the facts on the table, not all the vendor salespitch.
