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.

Ultimate Sealing for 4G63 Engines

Achieve a perfect seal on your high-boost 4G63 engine with the Cometic MLS (Multi-Layer Steel) Head Gasket. Specifically engineered for an 85.5mm bore and a compressed thickness of .075 inches, this gasket is the gold standard for Mitsubishi Eclipse, Galant, and EVO 1-3 builds.

Key Features & Benefits

  • Construction: Multiple layers of high-grade stainless steel
  • Coating: Viton rubber coating for superior heat resistance (up to 482°F)
  • Compatibility: Ideal for aluminum-to-aluminum or aluminum-to-cast iron blocks
  • Performance: Resists shearing forces and prevents blowouts under high boost
  • Installation: No additional sealants required

The Cometic MLS design utilizes embossed outer layers coated in Viton, a high-performance fluoroelastomer that ensures a leak-free seal even under extreme thermal cycling. By utilizing multiple layers of stainless steel, this gasket offers excellent rebound characteristics, allowing it to maintain a tight seal despite the expansion and contraction common in high-output turbocharged engines. Whether you are running a street-strip setup or a dedicated track machine, this gasket provides the durability needed to protect your engine block and cylinder head. Experience the precision engineering that makes Cometic the choice of professionals. Find all your essential engine build parts at GGCRACING.
