Unlock more power with the Skunk2 Thermal Intake Manifold Gasket designed specifically for the Honda B18C1 GSR (P72) engine. This gasket reduces heat soak, lowers intake air temperatures, and improves combustion efficiency, all of which lead to noticeable horsepower gains.

Constructed from Skunk2’s advanced high-temperature thermal polymer, this gasket blocks conductive heat transfer from the cylinder head to the intake manifold. Cooler air means more oxygen-dense combustion, resulting in up to 5% more power. A must-have for street, race, or boosted B-Series builds using the GSR intake manifold.
