I definitely did not buy this intake for expected gains in whp. And pairing it with an exhaust (which I DO plan to do... someday) will further lessen it's impact. For now, I'm content with the power I have. It was a blast to drive stock, so I have always been focused on making it look a little better and sound a little better. This intake was a good first step IMO since it is a little of both.
