The Big Mouth Air Dam is a perfect way to add some Performance to your 1984-1996 Corvette. It installs in about 45 minutes by removing the stock spoiler center bracket and drilling 4-1/8" holes in the skid bar. The Dam then fits on top of the lower radiator baffle and bolts in place. Included with the Powder Coated Dam is Stainless Steel Hardware and installation instructions.
