This precision-manufactured gasket features a compressed thickness of .098 inches and is designed for an 87mm bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .098-inch (2.49mm) compressed gasket thickness
• 87mm bore diameter designed for RB26DETT applications
• Exceeds OEM specifications for high-performance and high-boost applications
• Provides excellent heat resistance and combustion sealing

Cometic's MLS gaskets feature multiple layers of stainless steel with strategically placed embossments that create a superior seal around combustion chambers, coolant passages, and oil galleries. This gasket is particularly well-suited for modified RB26DETT engines running increased boost pressures or aftermarket engine management systems. The MLS design allows the gasket to recover and maintain sealing integrity through repeated heat cycles, making it an excellent choice for street, track, and drag racing applications.
