Cometic C4234-120 MLS Cylinder Head Gasket Bore Mitsubishi - 86mm 4G63 4G63T

The Cometic C4234-120 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 .120-inch (3.0mm) compressed thickness, making it ideal for turbocharged and high-compression builds that demand superior sealing under extreme conditions.

Key Features:

• Multi-Layer Steel construction provides exceptional strength and durability
• 86mm bore diameter optimized for 4G63/4G63T engines
• .120-inch compressed thickness for increased cylinder volume and lower compression
• Compatible with DOHC Mitsubishi 4G63 engines (Except Evo 4-9 models)
• Embossed stainless steel layers with Viton rubber coating for maximum sealing
• Resists blowout and combustion pressure leaks better than composite gaskets
• Designed to handle extreme temperatures and pressures in forced induction applications

Cometic's MLS gaskets are the professional choice for performance engine builders. The multiple layers of stainless steel provide the ability to rebound and seal surface imperfections while maintaining torque loading. This gasket is perfect for street performance, drag racing, and road racing applications where reliability and consistent sealing are critical. Note that this gasket is designed for pre-Evolution and non-Evolution 4G63 applications—it does not fit Evolution 4-9 models.
