The Cometic C4156-040 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Mitsubishi 4G63T turbocharged engines. This precision gasket features an 86mm bore diameter and .040" compressed thickness, designed to provide maximum sealing performance in high-boost forced induction applications.

Key Specifications:

• Multi-Layer Steel (MLS) construction for superior durability and blow-out resistance
• 86mm bore diameter optimized for performance builds
• .040" (1.02mm) compressed gasket thickness
• Engineered for DOHC 4G63T turbocharged engines
• Compatible with Mitsubishi Evolution IV through Evolution VIII (Evo 4-8)
• Stainless steel layers with advanced coating technology

Cometic MLS head gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that maintains superior sealing under extreme cylinder pressures and temperatures. The embossed sealing beads conform to surface imperfections while the MLS design allows for thermal expansion and contraction, making this gasket ideal for high-performance and racing applications where engine reliability is critical.

Application Note: This gasket is designed exclusively for Mitsubishi Evolution 4 through 8 models equipped with the DOHC 4G63T engine. Not compatible with earlier DSM (Diamond Star Motors) applications or Evolution 9+ models without verification.
