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 sealing component designed for large-displacement Chevy truck and SUV engines. This gasket seals the interface between the throttle body and intake manifold, preventing vacuum leaks that compromise fuel economy, idle quality, and throttle response. Whether you're performing routine maintenance, rebuilding an engine, or diagnosing a rough idle condition, this genuine MAHLE ORIGINAL/CLEVITE gasket ensures a factory-correct seal that meets GM engineering standards.

Manufactured by MAHLE ORIGINAL/CLEVITE—a trusted OEM supplier to General Motors—this throttle body gasket is engineered from high-temperature composite materials that resist thermal cycling and maintain compression over thousands of miles. The gasket's 5-inch x 8-inch dimensions are precision-engineered to fit the specific bolt pattern and port geometry of Chevy 6.0L, 6.2L, and 7.0L engines, creating a positive seal without requiring sealant. At just 0.066 lbs, the gasket's minimal mass reflects its thin, efficient design—exactly what experienced mechanics expect from factory gaskets that eliminate vacuum leaks at the source.

This gasket is essential for 2005–2015 Chevy Silverado, Suburban, Tahoe, and Avalanche owners running 6.0L, 6.2L, or 7.0L engines who experience hesitation, lean-condition codes (P0171/P0174), or vacuum-related drivability issues. Installation is straightforward: remove the throttle body, clean the gasket surfaces thoroughly with a plastic scraper, install the new gasket dry (no sealant needed), and torque bolts to spec. Technicians and DIY builders rely on MAHLE gaskets because they eliminate comebacks and preserve the precise air/fuel calibration these powerful engines demand.
