EngineQuest EN324 New Exhaust Manifold with A.I.R. Holes

The EngineQuest EN324 is a new cast exhaust manifold (also called an exhaust header manifold) that collects exhaust gases from the engine's cylinders and routes them into the exhaust system. It is sold as a single manifold.

Key Features:

• New exhaust manifold, not reclaimed
• Includes A.I.R. (air injection reaction) holes
• Sold individually (each)

A direct-replacement manifold like this is a way to restore exhaust flow and sealing when an original manifold is cracked or worn.
