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.

High-Performance Sealing for 4G63 Engines

Ensure your engine's integrity with the Cometic MLS (Multi-Layer Steel) Head Gasket. Engineered specifically for the Mitsubishi 4G63/T platform, this 85.5mm bore gasket features a compressed thickness of 0.030 inches, making it an ideal choice for high-output engine builds. Whether you are running a stock turbo or a high-boost setup, this gasket provides the reliability you need.

Advanced Construction and Benefits

  • Multi-Layer Stainless Steel: Multiple embossed layers provide superior strength and rebound capabilities.
  • Viton Coating: Outer layers are coated with heat-resistant Viton (up to 250°C/482°F) for a leak-free seal.
  • No Sealant Required: Designed for an easy, clean installation without the need for additional gasket dressing.
  • Versatile Compatibility: Perfectly handles the shearing forces between aluminum heads and cast iron or aluminum blocks.

This gasket is designed to withstand the extreme pressures of performance driving, ensuring your combustion chamber remains sealed under the most demanding conditions. Its corrosion-resistant properties mean it will maintain its seal over the long haul, protecting your investment from internal leaks.
