This precision-manufactured gasket delivers maximum sealing performance for high-output engine builds without requiring additional sealants.

Key Features:

• Multi-Layer Steel construction with embossed stainless steel layers for superior sealing
• 89.5mm bore diameter designed specifically for KA24DE applications
• .040 inch (1.02mm) compressed thickness for optimal compression control
• Proprietary high-temperature coating resists extreme combustion temperatures
• Reduces bore distortion and requires less clamp load than conventional gaskets
• Ideal for both aluminum-to-aluminum and aluminum-to-cast iron block configurations
• No sealants required for installation

Cometic MLS gaskets feature multiple embossed layers that conform to load distribution across the sealing surface, providing reliable performance in demanding conditions. The advanced material composition and precision manufacturing make this gasket suitable for street performance, racing, and boosted applications where cylinder pressure and temperatures exceed stock levels.
