Edelbrock 2733 Exhaust Crossover Plug Kit for Oldsmobile

The Edelbrock 2733 Exhaust Crossover Plug Kit provides essential protection for your Oldsmobile intake manifold installation. These replacement cast iron exhaust crossover plugs are designed to seal the exhaust crossover ports in cylinder heads when installing an Edelbrock Performer 455 intake manifold.

Key Features:

• Steel construction for durability and heat resistance
• Prevents manifold cracking caused by extreme exhaust heat during extended wide-open throttle operation
• Designed for Oldsmobile engines when using Performer 455 manifolds
• Supplied as a pair to plug both cylinder head crossover ports
• Light drive fit design ensures proper sealing

Installation: Use a file to finish and fit the plugs until they achieve a light drive fit in the exhaust crossover ports. Proper installation is critical to prevent exhaust heat from transferring through the cylinder heads into the intake manifold, which can cause manifold cracking and reduce performance.

These plugs are included with each Edelbrock Performer 455 manifold but are also available separately as replacement parts.
