Cometic H2754SP2040S MLS Head Gasket 91mm Bore .040 Inch Mazda MZR 2.3L

The Cometic H2754SP2040S is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed for Mazda MZR 2.3L engines with a 91mm bore diameter and .040 inch compressed thickness. This precision-engineered gasket delivers maximum sealing performance for high-output engines while requiring no additional sealants.

Multi-Layer Steel Construction:

• Comprised of three to five layers of stainless steel for increased strength, superior rebound capability, and excellent corrosion resistance
• Outer layers are embossed and coated on both sides with Viton rubber material designed to meet the demands of harsh sealing environments, varying load conditions, and different surface finishes
• Viton coating is heat resistant up to 250°C (482°F)
• Center shim layer uses uncoated stainless steel which allows for variable thickness requirements

Performance Benefits:

• Ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, withstanding the shearing forces created by dissimilar materials
• Provides superior sealing for turbocharged and high-compression applications
• Eliminates the need for additional sealants or gasket dressings
• Enhanced durability and reliability in demanding performance environments

The H2754SP2040S features a 91mm bore diameter with a compressed operating thickness of 0.040 inches, making it an excellent choice for performance builds, engine rebuilds, and applications requiring precise combustion chamber sealing.
