Cometic C4494-036 Cosworth BDG MLS Cylinder Head Gasket Bore - 91mm

The Cometic C4494-036 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Cosworth BDG engines. This high-performance gasket features a 91mm bore diameter and 0.036-inch compressed thickness, providing exceptional sealing capabilities for modified and high-output applications.

Key Features:

• Multi-Layer Steel construction for superior durability and heat resistance
• 91mm bore diameter optimized for Cosworth BDG engine specifications
• 0.036-inch (0.91mm) compressed thickness for precise compression ratio tuning
• Advanced embossment design ensures even clamping pressure across the sealing surface
• Withstands extreme cylinder pressures and temperatures in racing applications
• Maintains sealing integrity through thermal expansion and contraction cycles

Cometic MLS gaskets are constructed with multiple layers of stainless steel, featuring a Viton rubber coating that provides micro-sealing capabilities. This design allows the gasket to adapt to minor surface imperfections while maintaining combustion seal integrity. Ideal for racing, high-boost forced induction, and performance street applications where reliability is critical.
