Cometic C4254-075 MLS Cylinder Head Gasket Bore Honda - 89mm 075 H22A4 H22A7

The Cometic C4254-075 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda H22A4 and H22A7 engines. This precision-manufactured gasket features an 89mm bore diameter and a compressed thickness of .075 inches (0.75mm), making it ideal for stock rebuilds or mild performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
• 89mm bore diameter designed specifically for H22A4 and H22A7 engine blocks
• .075" compressed thickness for precise compression ratio control
• Advanced coating technology ensures optimal sealing between head and block surfaces
• Eliminates the need for additional sealants or re-torquing after initial installation
• Engineered to withstand extreme temperatures and combustion pressures

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, with embossed sealing beads around combustion chambers, coolant passages, and oil return holes. This design allows the gasket to adapt to minor surface imperfections while maintaining superior combustion sealing. The gasket's ability to rebound ensures consistent clamping force throughout the engine's thermal cycles, making it an excellent choice for both street and performance applications.
