Throttle Body Gasket 09-21 Hemi 5.7L

The Throttle Body Gasket for 2009-2021 Hemi 5.7L engines is a critical OEM-equivalent seal that prevents vacuum leaks and maintains precise fuel-air mixture control in your engine's intake manifold. Whether you're running a stock Ram, Jeep, or Dodge with the legendary 5.7L Hemi powerplant or you're mid-restoration, a compromised throttle body gasket leads to rough idle, lean conditions, and unpredictable performance. This MAHLE Original component is engineered to factory specifications, ensuring your fuel system and engine management operate as designed without air bypass at the throttle body mounting surface.

Manufactured by MAHLE ORIGINAL/CLEVITE—a tier-one OEM supplier trusted by major automakers—this gasket uses precision-molded elastomer construction to create a reliable seal under the thermal and pressure cycling typical of Hemi operation. The gasket's micro-texture surface conforms to both the throttle body casting and intake manifold face, eliminating gaps that allow unmetered air to bypass the mass airflow sensor. At just 0.005 inches thick, this ultra-precision component must match OEM thickness and material properties exactly; aftermarket substitutes often fail prematurely under Hemi heat cycles, leading to repeated replacement costs.

Technicians and enthusiasts rebuilding or diagnosing Hemi 5.7L engines benefit most from selecting genuine MAHLE gaskets when throttle body removal is required for cleaning, fuel injector service, or intake valve work. Installation is straightforward—remove the old gasket completely, clean both mating surfaces with a bristle brush and carburetor cleaner, and position the new gasket before rebolting the throttle body. Compatible across 2009–2021 model years, this gasket is essential during any major intake work and recommended whenever throttle body removal exposes an aged or questionable seal, preventing costly drivability issues down the road.
