Prevent heat from transferring from the heads to the intake manifold and throttle body!

Improve airflow by eliminating the need for OEM gaskets, which are not matched to your ports.  All NWP Phenolic Spacers are port matched to your stock intake ports!  A smooth transition from one intake manifold to another is very important for optimal airflow.  Don't be fooled by other "thermal gaskets" that aren't properly matched to your intake ports!  They are usually just a copy of the OEM gasket.

Experience an intake manifold that's cool to the touch!
Experience a better quality product with NWP!

Gains of 8hp and 9ft-lb of torque! (Dyno Sheet)
Average intake manifold temperature decrease of 43 degrees!
