Product Details

The Cometic C4234-140 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Mitsubishi 4G63 and 4G63T engines. This gasket features a .140" (3.56mm) compressed thickness and an 86mm bore diameter, making it ideal for performance builds and engine rebuilds requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and boost
  • .140" compressed thickness allows for precise compression ratio tuning
  • 86mm bore diameter optimized for stock and mild performance applications
  • Designed for DOHC 4G63/4G63T engines (excludes Evolution 4-9 models)
  • Advanced coating technology resists corrosion and maintains clamping force
  • Accommodates engine movement and cylinder distortion better than traditional composite gaskets

Cometic MLS gaskets are a popular choice among performance enthusiasts and engine builders for turbocharged and high-horsepower applications. The multiple layers of stainless steel with proprietary coatings provide exceptional resistance to blowout and ensure a reliable seal between the cylinder head and engine block. This gasket is compatible with various Mitsubishi platforms including DSM (Diamond Star Motors) vehicles, Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser models equipped with the 4G63 engine.

Application Note: This gasket fits 4G63/4G63T DOHC engines except Mitsubishi Evolution 4-9 models. Verify bore size and thickness requirements for your specific build.
