Gasket LS Throttle Body 92mm/102mm

The Gasket LS Throttle Body 92mm/102mm is a precision composite gasket engineered for GM LS-series engines and compatible throttle body applications. This essential component seals the interface between your intake manifold and throttle body, preventing vacuum leaks that compromise fuel economy, idle quality, and overall engine performance. Whether you're building a high-output LS engine from the ground up or refreshing an existing powerplant, a quality gasket replacement is a critical step that separates a solid rebuild from a mediocre one.

Manufactured by Holley, this throttle body gasket features a durable composite construction designed to withstand the heat and pressure cycles of modern LS engines without degradation or premature failure. The 92mm and 102mm design accommodates both smaller-displacement and larger-bore throttle body variants commonly paired with LS swaps and factory replacements. Unlike cheap cork or paper alternatives, composite gaskets maintain their structural integrity across repeated thermal cycles, seal consistently against both aluminum and cast-iron surfaces, and resist fuel and oil absorption that causes leakage over time.

Mechanics and engine builders trust Holley gaskets because they eliminate the guesswork and frustration of vacuum leaks during dyno tuning and road testing. If you're installing a carbureted or throttle-body fuel-injected LS engine, upgrading to an LS swap intake manifold, or simply replacing a failed gasket on existing equipment, this composite gasket delivers reliability without compromise. Always replace gaskets during disassembly—reusing old gaskets invites air leaks that throw off fuel mapping and create hard-start or idle issues that mask the real culprit.
