Precision Sealing for 4G63 Performance

Maximize the reliability of your 4G63 engine with the Cometic MLS Head Gasket. Featuring an 86mm bore and a compressed thickness of .051 inches, this gasket is engineered to handle the high pressures and temperatures associated with modified Mitsubishi Eclipse, Galant, and Talon engines.

Why Choose Cometic MLS?

  • Multi-Layer Steel: Superior strength and durability
  • Viton Coating: Heat-resistant fluoroelastomer for a leak-proof seal
  • Versatile Fitment: Compatible with aluminum and cast iron surfaces
  • No Sealant Needed: Designed for a quick, clean installation
  • Resilience: Excellent rebound and corrosion resistance

Cometic's MLS gaskets are the industry standard for high-output engines. The embossed stainless steel layers provide the necessary spring-back to maintain a seal even when the cylinder head lifts slightly under extreme boost. The Viton coating on both sides ensures that the gasket conforms to minor surface imperfections, providing a reliable seal every time. This .051-inch thickness is ideal for those looking to maintain specific compression ratios while ensuring the head remains securely fastened to the block. Whether you are daily driving a modified GST or racing a dedicated GSX, this gasket offers the peace of mind you need. Find the perfect fit for your Mitsubishi build with the expert selection at GGCRACING.
