• LOWER INTAKE TEMPS, GUARANTEED!

    Average testing shows a 25% drop in intake temperatures resulting in a 5% increase in horsepower.

FEATURED APPLICATIONS

FIND YOUR APPLICATION

LOWER TEMPS, GUARANTEED

Thermalnator gaskets directly replace your stock intake manifold gasket. Their advanced cooling properties completely stop metal-to-metal contact between the intake manifold and the engine block, acting as an intercooler for your intake.

BY THE NUMBERS

Denser Air = More Power: Every 5°F increase in air temperature reduces density by 1%. Our gaskets maximize density by fighting heat soak.

Prover Temperature Drops: Average tests show a 25°F drop in intake temperatures, with some applications seeing up to a 35° drop.

Direct Bolt-On: The 1/8″ (0.125″) phenic polymer design allows you to retain factory hardware.

PREMIUM QUALITY, NO COMPROMISE

Extreme Durability: Formulated with the highest melting point to prevent deformation.

Made in the USA: Precision CAD-designed and manufactured locally by Sikky Manufacturing for the highest quality and perfect fitment.
