performance wise it probably adds between 8-10 HP which is pretty much un-noticable. The whole intake is CF, and even leads to one of the ducts in the front of the car being CF. Its an incredible sexy look. The sound is ridiculous. Its a mean mean roar at low RPMs and only gets nicer as you step on it. Its for sure pricey, but I thought it was money well spent. The only reason its for sale is because you cant have the intake and the SC at the same time. If you would like pictures let me know.
