Throttle Body Gasket 09-21 Hemi 5.7L

The Throttle Body Gasket 09-21 Hemi 5.7L is a critical engine seal engineered for owners and technicians maintaining late-model Dodge, Jeep, and Ram vehicles powered by the legendary 5.7L Hemi platform. This OEM-specification gasket prevents vacuum leaks, fuel vapor escape, and coolant seepage at the throttle body interface—failures that cause rough idle, hesitation, and check engine codes. Whether you're diagnosing a P0171 system-too-lean fault or performing preventive maintenance on a high-mileage Charger, Wrangler, or 1500, this gasket delivers the seal integrity that stock applications demand.

Manufactured by MAHLE ORIGINAL/CLEVITE under part number G32511, this gasket is engineered from multi-layer composite material designed to withstand Hemi operating temperatures and intake manifold clamping forces without permanent set or degradation. The ultra-thin profile (0.005 inches) ensures precise surface contact at the throttle body mounting face, eliminating the micro-leakage paths that compromise combustion efficiency and trigger emissions diagnostics. Unlike inferior aftermarket alternatives, MAHLE's gasket maintains a consistent seal across the full 2009–2021 production span, accommodating minor casting and bolt-torque variations across model years while resisting fuel, coolant, and oil breakdown.

This gasket is essential for any 5.7L Hemi owner experiencing stumbling on cold starts, idle surge, or hesitation during light throttle transitions—symptoms commonly rooted in vacuum leaks rather than fuel delivery or ignition faults. Installation requires only basic hand tools and 10–15 minutes; simply unbolt the throttle body from the intake manifold, remove the old gasket, and install the new seal with factory-specification torque values (typically 7–10 ft-lbs). Technicians and DIY builders performing valve cover gasket kits, intake gasket sets, or complete fuel system overhauls should always replace the throttle body gasket simultaneously to avoid repeat disassembly and ensure maximum system performance.
