New factory replacement vacuum block gasket. Quanity (1). These will fit both stock and aftermarket aluminum assemblies. We offer them in 2 different options: 1984-1985 (Hot Air) or 1986-1987 (Intercooled) application.
These are designed to be extra thick and made of a high temperature composite that will crush for a perfect seal and last a lot longer. This is a specialty gasket that you will not find at your local parts store.
Whenever removing your vacuum block assembly (for service or replacement), it is always recommended to replace this gasket and never reassemble without one.
For best results, always make sure both surfaces are clean and true.
Over long periods of time, mileage and heat break down the material which can cause a major leak.
