M&H Rear Galley Plug is a precision-machined aluminium oil diverter barbell designed for Chevrolet / Holden LS Gen III & Gen IV engines. This upgraded barbell replaces the factory plastic plug, offering improved durability and more efficient oil control for performance engines, rebuilds, and high-RPM applications.

With an integrated oil bypass delete, this barbell ensures that 100% of the engine oil is routed through the filter, completely eliminating the risk of dirty or unfiltered oil bypassing the system. The improved internal flow path enhances lubrication consistency throughout the engine, supporting better bearing protection and long-term reliability.

As a direct replacement for the OEM plastic barbell, installation is straightforward and requires no modifications—making it an essential upgrade during any LS engine build or refresh.
