SUBARU EJ 25 4.060 X .080 PRO COPPER HD GSKT

The SCE Pro Copper Head Gasket is a performance head gasket designed for EJ25 engines. It features a 4.060-inch bore and a 0.080-inch compressed thickness. Crafted from premium 99 percent pure copper sheets, these gaskets are precisely rolled and tested for uniform flatness to ensure proper cylinder head-to-block alignment and prevent uneven loading.

After processing, each gasket is annealed for optimal mating and improved cylinder sealing, resulting in lower leak-down percentages. O-ringing is recommended for these gaskets. SCE offers Pro Copper gaskets in various bore and thickness combinations to meet specific performance requirements.
