Cometic C4591-056 MLS Cylinder Head Gasket Bore Mitsubishi DOHC - 87mm 4G63T

The Cometic C4591-056 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for the Mitsubishi 4G63T turbocharged engine. Designed with an 87mm bore diameter and .056" compressed thickness, this gasket is precision-manufactured to provide exceptional sealing performance in high-performance and forced induction applications.

Key Specifications:

• Bore Size: 87mm
• Compressed Thickness: .056 inch (1.42mm)
• Construction: Multi-Layer Steel (MLS)
• Engine Application: Mitsubishi 4G63T DOHC turbocharged
• Vehicle Compatibility: Mitsubishi Lancer Evolution IV, V, VI, VII, and VIII (Evo 4-8)

Features and Benefits:

• Multi-layer steel construction provides superior durability and resistance to combustion pressure
• Engineered to withstand extreme cylinder pressures in turbocharged and modified applications
• Precise bore dimensions ensure optimal combustion chamber sealing
• Maintains consistent clamping load across the entire sealing surface
• Resists gasket failure from thermal cycling and detonation

Cometic MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to minor surface imperfections while maintaining positive sealing. This design makes them ideal for engines running increased boost pressures, aggressive tuning, or high compression ratios. The .056" thickness allows for fine-tuning of compression ratio and piston-to-valve clearance in modified applications.

Important Note: This gasket is specifically designed for Evolution IV through VIII models with the DOHC 4G63T engine. Verify your engine specifications and bore size before ordering to ensure proper fitment.
