Cometic C4494-045 Cosworth BDG MLS Cylinder Head Gasket Bore - 91mm

The Cometic C4494-045 is a Multi-Layer Steel (MLS) cylinder head gasket specifically engineered for Cosworth BDG engines. This precision gasket features a 91mm bore diameter and .045" compressed thickness, designed to deliver superior sealing performance in high-performance and racing applications.

Key Features:

• Multi-Layer Steel construction for maximum durability and heat resistance
• 91mm bore diameter optimized for Cosworth BDG engine specifications
• .045" (1.14mm) compressed gasket thickness
• Advanced MLS design provides excellent recovery and conformability
• Superior sealing under extreme cylinder pressures and temperatures
• Eliminates gasket failure from lifting, splitting, and thermal distortion

Cometic MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to sealing surface imperfections while maintaining consistent clamping pressure. This design makes them ideal for turbocharged, supercharged, and high-compression racing engines where stock gaskets cannot withstand the extreme conditions.
