Cometic C4213-050 Mitsubishi 4G64 Copper Head Gasket 88mm Bore .050 Thick

The Cometic C4213-050 is a precision-engineered copper cylinder head gasket designed specifically for Mitsubishi 4G64 engines. This high-performance gasket features an 88mm bore diameter and .050" (0.050 inch) compressed thickness, making it ideal for performance builds and engine rebuilds requiring precise compression control.

Key Specifications:

• Material: Copper construction for superior heat dissipation and sealing
• Bore Size: 88mm diameter
• Compressed Thickness: .050 inch (1.27mm)
• Application: Mitsubishi 4G64 engines
• Design: Solid copper gasket for maximum conformability

Cometic's copper head gaskets are manufactured from high-quality oxygen-free copper, providing excellent thermal conductivity and the ability to withstand extreme cylinder pressures. The copper material conforms to cylinder head and block imperfections better than traditional multi-layer steel gaskets, creating a superior seal. This gasket is particularly well-suited for turbocharged, supercharged, or high-compression applications where reliability is critical.

Benefits:

• Superior sealing properties under high combustion pressures
• Excellent heat transfer capabilities reduce hot spots
• Reusable when properly maintained and annealed
• Precise thickness control for accurate compression ratio tuning
• Proven performance in racing and high-output applications

The .050" thickness makes this gasket suitable for stock deck heights or mild performance applications. Installation requires proper surface preparation with both cylinder head and block surfaces machined to a smooth finish (recommended RA value of 50-60 microinches). Copper gaskets typically require an appropriate sealant and should be installed following Cometic's torque specifications and procedures.
