Skunk2 Racing thermal throttle body gasket for Acura K20A2/A3/Z1 and Honda K20A3/Z3 K-Series with a 70mm throttle body opening. The thermal polymer reduces heat transfer into the intake manifold, lowers incoming air temperature to help resist heat soak, and is intended for street, weekend or race use; Skunk2 indicates this approach can provide up to roughly 5% more power in supported setups.
