The Skunk2 Thermal Throttle Body Gasket for Pro Series 70mm throttle bodies (PRB-style K-Series) is engineered to reduce heat soak, lower incoming air temperatures, and improve engine performance by limiting heat transfer from the intake manifold to the throttle body. Constructed from high-temperature thermal polymer, this gasket delivers better combustion conditions and can help unlock up to 5% more power.

Ideal for high-performance K-Series builds, this thermal gasket is a simple and cost-effective upgrade for street, race, or forced induction applications. It is compatible with both hard and black anodized Skunk2 Pro Series 70mm throttle bodies.
