Cometic C4342-066 MLS Cylinder Head Gasket for Subaru Bore - EG33 102mm

The Cometic C4342-066 is a precision-engineered multi-layer steel (MLS) cylinder head gasket designed specifically for the Subaru EG33 3.3L horizontally-opposed six-cylinder engine. This high-performance gasket features a 102mm bore diameter and a compressed thickness of .066 inches (1.68mm), making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-layer steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures and temperatures
• 102mm bore diameter optimized for the Subaru EG33 engine platform
• .066-inch compressed thickness for precise compression ratio tuning
• Embossed stainless steel layers with elastomeric coating ensure excellent conformability to cylinder head and block surface imperfections
• Superior resistance to combustion gases, coolant, and oil compared to traditional composite gaskets
• Designed to handle high-performance and boosted applications

Cometic MLS gaskets are the preferred choice for performance engine builders due to their ability to withstand extreme heat and pressure while maintaining a reliable seal. The advanced multi-layer design allows the gasket to move with the engine's thermal expansion and contraction, reducing the risk of gasket failure. Perfect for EG33 engines found in Subaru SVX models and engine swap applications.
