Throttle Body Gasket 05-15 Chevy 6.0 6.2 7.0L

The Throttle Body Gasket 05-15 Chevy 6.0 6.2 7.0L (MPN G31963) is a critical OEM-specification seal engineered for GM LS-series engines during model years 2005 through 2015. This gasket prevents vacuum leaks between the throttle body and intake manifold—a common failure point that degrades idle quality, fuel economy, and throttle response. Whether you're rebuilding a stock engine, restoring a high-mileage truck, or maintaining a modified LS platform, this MAHLE ORIGINAL/CLEVITE gasket delivers the precision fit and durability that professional mechanics and enthusiasts trust for reliable performance.

Manufactured by MAHLE ORIGINAL, a Tier-1 OEM supplier, this rubber gasket is engineered to withstand thermal cycling, fuel exposure, and engine vibration without degradation or compression set. The 5 x 8 inch gasket profile ensures perfect sealing geometry between the throttle body casting and manifold surface, eliminating parasitic air leaks that would otherwise trick the mass airflow sensor and oxygen sensors, causing lean-running conditions and check engine codes. At just 0.066 pounds, the gasket's minimal mass reflects precision engineering—no excess material, only what's needed for a reliable seal that lasts the life of the engine.

This gasket is essential for anyone performing throttle body removal, intake manifold service, or engine rebuild on Chevy trucks, Tahoes, Suburbans, and performance cars equipped with the 6.0L, 6.2L, or 7.0L LS engines. Installation is straightforward—simply remove the old gasket, clean the mating surfaces with a gasket scraper to bare aluminum, and install the new seal with light torque on the throttle body mounting bolts. Using an OEM-specification gasket like this MAHLE unit ensures you won't introduce vacuum leaks or drivability issues that plague inferior aftermarket alternatives, making it the smart choice for single-service repairs or long-term engine reliability.
