Weapon R Mitsubishi Evo 4-6 4G63 Cylinder Head Intake Manifold Thermal Gasket

This is the Weapon R intake manifold thermal gasket for your Mitsubishi Evo 4 through 6, specifically for the 4G63 engine. Its main job is to go between your cylinder head and intake manifold, acting as a barrier to heat transfer. By reducing the amount of heat that gets into the intake manifold from the hot cylinder head, it helps keep the incoming air charge cooler. Cooler air is denser air, and denser air means a better air-fuel mixture for more efficient combustion.

Weapon R makes this gasket from a durable material designed to withstand the high temperatures found in the engine bay. It's a well-built piece that fits right into place, helping to seal the intake tract effectively. Installing this gasket is a straightforward way to make a small but notable improvement in intake air temperature management, which can contribute to better engine performance, especially if you've made other modifications to your Evo.
