Product Details

The Cometic C4234-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Mitsubishi 4G63 and 4G63T DOHC engines. This precision gasket features an 86mm bore diameter and .040" (1.02mm) compressed thickness, making it an excellent choice for modified and turbocharged applications requiring enhanced sealing and durability.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and resistance to blown head gaskets
  • 86mm bore diameter accommodates stock and mildly overbored applications
  • .040" compressed thickness allows for fine-tuning compression ratios
  • Designed for DOHC 4G63 and 4G63T engines (excludes Evolution 4-9 models)
  • Embossed stainless steel layers with Viton rubber coating ensure optimal sealing
  • Engineered to withstand extreme cylinder pressures in turbocharged and high-performance builds

Cometic MLS gaskets are a proven choice for enthusiasts building reliable, high-output Mitsubishi engines. The multi-layer design allows for micro-movement between layers while maintaining superior combustion sealing, making this gasket ideal for street performance and competition applications. Compatible with various 4G63/4G63T-powered vehicles including DSM (Diamond Star Motors) platforms and older generation Mitsubishi models.
