The Hondata Intake Manifold Heatshield is an absolute must for every high performance S2000 application. The heatshield replaces the factory intake manifold gasket with a high density plastic gasket that reduces thermal transfer from the cylinder heads and cooling system.
As a result, intake manifold temperatures are greatly reduced. Lower temperatures result in higher air density resulting in more power and reduced chance of engine detonation. We recommend the insulator for every forced induction application and highly recommend it for high performance NA engines.
