Throttle Body Gasket 97-16 Chevy LS

The Throttle Body Gasket 97-16 Chevy LS is an OEM-quality sealing component engineered for LS-series powered vehicles spanning nearly two decades of production. This gasket serves a critical function: preventing vacuum leaks and coolant seepage at the throttle body mounting interface—a common failure point in high-mileage or modified LS engines. Whether you're rebuilding a stock 5.3L truck, restoring a vintage Camaro, or finalizing a custom engine swap, this MAHLE ORIGINAL gasket ensures reliable throttle body installation and maintains the precise air-fuel ratios your tuning demands.

Manufactured by MAHLE ORIGINAL/CLEVITE, a supplier trusted by GM engineers, this rubber gasket features precision-molded geometry that matches the throttle body and intake manifold port patterns exactly. The material composition resists thermal cycling, engine coolant degradation, and the elevated under-hood temperatures common to turbocharged or supercharged LS builds. At just 0.005 inches thick, it provides optimal compression when torqued to spec, eliminating the vacuum leaks that can cause rough idle, lean surge, or drivability issues that are difficult to diagnose. The gasket's compact 5 x 8 inch footprint fits all LS variants—LS1, LS2, LS3, LS7, 5.3L, 6.0L, and 6.2L engines—without modification.

This gasket is essential for any technician or enthusiast performing throttle body removal, intake manifold work, or engine reassembly on 1997–2016 GM LS platforms. Installation is straightforward: remove the old gasket completely, clean the mating surfaces with a solvent to remove carbon and debris, position the new gasket, and torque the throttle body bolts in a cross pattern to manufacturer specifications. Replace this gasket whenever you remove the throttle body—reusing old gaskets risks subtle leaks that compromise idle quality and engine management feedback. This single-gasket pack is ideal for one-time repairs, restorations, or preventive maintenance on any LS engine, whether stock or modified.
