LS Oil Galley Plug OE Style Nylon

The ALLSTAR PERFORMANCE LS Oil Galley Plug OE Style Nylon is a direct replacement component designed for LS-series engine builders and performance enthusiasts who require factory-spec reliability during custom builds and modifications. This plug is essential for sealing off unused gallery ports during engine refreshes, ensuring a secure, leak-free seal as specified by OEM engineers.

Constructed from durable nylon material, this OE-style galley plug adheres to Chevrolet's original specifications for thread fit and sealing surface. The nylon composition is resistant to oil degradation and maintains dimensional stability across varying temperatures, eliminating corrosion concerns associated with steel alternatives. This ensures that the plug performs reliably under various conditions, including high-rpm tuning and boosted applications.

Engine builders working on LS1, LS2, LS3, LS9, and truck-platform variants will find this plug particularly beneficial. Its design integrates seamlessly into tight engine compartments without adding unnecessary weight or requiring modifications to existing port lines. This makes it an ideal choice for anyone looking to maintain the integrity of their LS engine builds.
