Throttle Body Gasket 03-15 Dodge 5.7L Hemi

The Throttle Body Gasket 03-15 Dodge 5.7L Hemi from Cometic Gaskets is a critical engine seal engineered for third-generation Mopar Hemi platforms. This OEM-specification gasket prevents vacuum leaks and fuel vapor escape at the throttle body interface, where intake manifold meets the air induction system. Any deterioration or failure in this gasket compromises idle quality, throttle response, and fuel economy—making replacement essential during routine maintenance or when upgrading induction components.

Cometic's Throttle Body Gasket for the 5.7L Hemi features a reinforced rubber construction formulated to withstand thermal cycling and high intake manifold temperatures without degradation. The gasket's precision-molded dimensions ensure a tight, consistent seal across the throttle body mounting surface, preventing the micro-leaks that often cause rough idle and diagnostic trouble codes. Lightweight at just 0.06 lbs with compact dimensions of 6 x 0.4 x 7.1 inches, it installs directly between the throttle body and intake manifold without modification.

This gasket is ideal for Dodge Ram, Charger, and Magnum owners running the legendary 5.7L Hemi V8 throughout the 2003 to 2015 model years. Whether rebuilding after throttle body cleaning, replacing a failed original gasket, or assembling a fresh induction setup, this part is a necessity for any serious Hemi builder or daily-driver maintenance program. Installation requires only basic hand tools and takes under 15 minutes, making it one of the highest-return gasket replacements for drivability and reliability.
