Skunk2 thermal throttle-body gasket is a high-temperature thermal-polymer insulator that sits between the throttle body and intake manifold to block heat soak. Lowering the air temperature before it reaches the cylinder head feeds the engine cooler, denser air for combustion — worth up to ~5% more power on a built setup. Gasket only.
