Airhorn gasket is the most abused gasket on the Rochester Dualjet carburetor. When removed for jet or tuning changes old brittle gasket breaks. If you're going to go inside your carburetor, it best to have a couple of these extra thick gaskets on hand. Doubling up gaskets can also help seal a warped Dualjet air horn assembly.
Quantity: 2 gaskets.
