New factory replacement upper plenum (dog house / bonnet) gasket. Quanity (1). This gasket seals your your upper plenum to your lower intake manifold. We offer them in 3 different options: Stock (w/ egr), Stock (non-egr) and Champion Racing / Bowling Green Customs.
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 upper plenum (for service or replacement), it is always recommended to replace this gasket and never reassemble without one.
Over long periods of time, mileage and heat break down the material which can cause a major leak.
For best results, always make sure both surfaces are clean and true.
Fits all 1986-1987 LC2 (intercooled) Turbo Regal applications.
