About Cometic Gasket

Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.

Precision Sealing for High-Performance 4G63

The Cometic MLS (Multi-Layer Steel) Head Gasket in .066-inch thickness is specifically designed for the Mitsubishi 4G63 engine found in the EVO 4-9. When building a high-performance engine, maintaining a consistent seal is critical to preventing head gasket failure under boost. This gasket features a robust multi-layer stainless steel construction that provides the necessary strength to withstand the extreme cylinder pressures generated by tuned engines.

Key Features and Benefits

  • Compressed Thickness: .066 inch
  • Bore Size: 86mm
  • Material: Multi-Layer Stainless Steel
  • Coating: Viton Rubber (Heat resistant to 482°F)
  • Compatibility: Mitsubishi 4G63 (EVO 4-9)

The outer layers are embossed and coated with Viton, a high-performance fluoroelastomer that ensures a leak-proof seal even on surfaces that are not perfectly smooth. This gasket is designed to rebound and resist corrosion, making it a reliable choice for both street-driven and track-only vehicles. Because it is a multi-layer design, it handles the thermal expansion and contraction of the cylinder head and block without losing its seal integrity. Whether you are performing a routine rebuild or a full engine overhaul, this Cometic gasket provides the peace of mind you need. Enhance your engine's reliability with high-quality parts from GGCRACING.
