Cometic C4254-051 MLS Cylinder Head Gasket Honda Bore - H22A4 H22A7 89mm 051 Inch

The Cometic C4254-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for 1997-2001 Honda Prelude engines equipped with H22A4 or H22A7 VTEC powerplants. Featuring an 89mm bore diameter and .051 inch (1.3mm) compressed thickness, this gasket delivers maximum sealing performance for naturally aspirated, turbocharged, or nitrous-fed applications.

Multi-Layer Steel Construction:

• Comprised of three layers of stainless steel for superior strength and durability
• Outer layers are embossed and coated with Viton fluoroelastomer material on both sides
• Viton coating is heat resistant up to 482°F (250°C) for extreme sealing environments
• Center shim layer is uncoated stainless steel that can be varied for thickness requirements
• Excellent rebound characteristics and corrosion resistance

Performance Benefits:

• Ideal for both aluminum-to-cast iron and aluminum-to-aluminum block applications
• Withstands shearing forces created by dissimilar metal expansion rates
• Reduces bore distortion through even torque load distribution
• No sealants required for installation
• No re-torque necessary after initial installation
• Not designed for use on engines with O-rings or receiver grooves

This gasket provides a superior seal compared to traditional composite or copper gaskets, making it the preferred choice for performance builders and racers seeking reliability under extreme cylinder pressures.
