Cometic MLS Head Gasket 85.5mm Bore .066" for Mitsubishi/Eagle 1989-2006 (4G63/T)

Fits 1989-2006 Mitsubishi Eclipse, Galant, Lancer Evolution, and Eagle Talon (4G63/T).

This Cometic MLS (Multi-Layer Steel) Head Gasket is engineered for high-output 4G63/T engines, providing a superior seal without the need for additional sealants. The 85.5mm bore and 0.066-inch compressed thickness make it an ideal choice for performance builds requiring precise compression ratios and reliable high-pressure sealing. Constructed from multiple layers of embossed stainless steel, this gasket offers exceptional rebound characteristics and resistance to corrosion.

The outer layers are coated with a Viton fluor elastomer rubber, capable of withstanding temperatures up to 250°C (482°F). This advanced coating ensures a reliable seal across various surface finishes and load conditions, while the stainless steel shim layers effectively manage the shearing forces between aluminum heads and cast iron or aluminum blocks. By requiring less clamp load, this gasket helps reduce bore distortion during installation.
