Tomei Performance Metal Head Gasket – 86.5 mm Bore, 1.8 mm Thickness for Mitsubishi 4G63 Engine (Evo IV–IX)

Description

Adoption of super grommet:
The head gasket series for TOMEI 4G63 improves sealing performance by adopting a super grommet type with outstanding reliability.

Super grommet type:
The dual seal system of the bead structure and metal grommet maximizes the gas seal performance around the bore as well as the cooling water and oil seals.

Thermal conductivity and strength of stainless steel:
By using stainless steel with high thermal conductivity for the gasket material, the heat at the upper end of the cylinder block can be transferred to the cylinder head side for effective cooling. Since it does not become hot locally, it is difficult for blow-by to occur.
In addition, since stainless steel has high strength, it is advantageous against blow-through, and the joint rigidity between the head and block can be increased. A strong connection between the head and the block increases the rigidity of the entire engine, reduces torsion and bending, and improves the durability of the moving part bearings.

About marking:
All TOMEI metal head gaskets are marked with the model, bore, thickness, and TOMEI POWERED INC. logo.
Please check the logo carefully and beware of imitations and similar products claiming to be made by Tomei Powered.
