Cometic C4494-080 Cosworth BDG MLS Cylinder Head Gasket Bore - 91mm

The Cometic C4494-080 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Cosworth BDG engines. This precision-manufactured gasket features a 91mm bore diameter and .080" (2.0mm) compressed thickness, providing exceptional sealing performance for high-performance and racing applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• 91mm bore diameter designed for Cosworth BDG engine specifications
• .080" compressed thickness for precise compression ratio tuning
• Advanced material technology prevents gasket failure under extreme heat and pressure
• Provides excellent sealing characteristics for high-boost and high-compression applications
• Engineered to withstand thermal expansion and contraction cycles

Cometic gaskets utilize multiple layers of stainless steel with specialized coatings to ensure optimal sealing under the demanding conditions of racing and performance engines. The MLS design allows for engine movement and provides consistent clamping pressure across the entire sealing surface, making this gasket ideal for turbocharged, supercharged, and naturally aspirated Cosworth BDG builds.
