Yep and thats how they get you. They figure you can get the same results with thier intake, just slap it on and dial in your car. "YEAH RIGHT', like it's that easy for use without a dyno. Lets face it, the stock air boxes aren't that restrictive these days. There's a little to be had with an intake, but most of it is with a tune. Putting on an intake without a tune is sorta pointless and is really a waste of money.
