MRC Racing Components Thermal Intake Manifold Gasket K20 K24

Make more power by keeping intake heat where it does not belong. The MRC Racing Components Thermal Intake Manifold Gasket for K20 and K24 engines is manufactured from high-grade temperature-insulating material and precision-cut to replace the factory intake manifold gasket. By insulating the intake manifold from engine block heat, this gasket helps lower intake air temperatures for a denser air charge and more consistent power output.

Thermal Intake Gasket Features

• High-Grade Thermal Insulation — Blocks heat transfer from the cylinder head to the intake manifold
• Precision Cut — Direct replacement for OEM K20 and K24 intake gaskets
• Lowers Intake Air Temperatures — Cooler air is denser, which means more power
• Direct Bolt-On — No modification required
• Lightweight Construction — No measurable weight penalty

Fitment / Applications

• Honda K20 engines (RSX Type-S, EP3 Civic Si, TSX, etc.)
• Honda K24 engines (Accord, Element, TSX, CR-V, etc.)
• K-series engine swaps in any chassis

Notes

• Replaces the OEM intake manifold gasket directly
• Works with both stock and aftermarket intake manifolds
• Recommended to replace any time you remove the intake manifold

Pro Tip: A thermal intake gasket is one of the most cost-effective performance upgrades for a K-series engine. The factory metal gasket conducts heat directly from the head into the intake manifold, raising IATs. This thermal barrier breaks that heat path, and the gains are measurable — especially on hot days or in tight engine bays where heat soak is a problem.
