Aeroflow Performance supercharger gaskets are designed to keep the boost going down into the manifold without any leakage. These are made from a thick .062" material which allows a more compressible gasket. This ensures your blower is well sealed whenever your engine is running. The gaskets suit either 6-71, 8-71 or 10-71 blower cases and available in either a single pack or a bulk pack of 10.
