Product Details

The Cometic C4157-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the Mitsubishi 4G63T turbocharged engine found in Evolution IV through VIII models. This precision-machined gasket features an 85mm bore diameter and .066" (1.68mm) compressed thickness, making it ideal for engines running increased boost pressure or modified compression ratios.

Key Specifications:

  • Bore Size: 85mm (3.346")
  • Compressed Thickness: .066" (1.68mm)
  • Construction: Multi-Layer Steel (MLS)
  • Engine: Mitsubishi 4G63T DOHC
  • Application: Evolution IV, V, VI, VII, VIII (Evo 4-8 ONLY)

Features & Benefits:

  • Multi-layer steel construction provides superior sealing under extreme cylinder pressures
  • Accommodates thermal expansion and head/block movement better than composite gaskets
  • .066" thickness helps maintain proper compression ratio for turbocharged applications
  • Embossed stainless steel layers with specialized coatings ensure reliable combustion sealing
  • Designed to withstand high boost and performance modifications

Cometic MLS head gaskets are a popular choice for enthusiasts building high-performance 4G63T engines, offering the durability needed for track use, drag racing, and high-horsepower street applications. Professional installation and proper surface preparation (RA finish of 50-60) are recommended for optimal performance.
