Cometic H1340SP2043C 84.5mm .043in Copper Head Gasket Honda Civic CRX VTEC

The Cometic H1340SP2043C is a high-performance copper head gasket designed specifically for Honda Civic and CRX applications with Integra VTEC cylinder heads. This precision-engineered gasket features an 84.5mm bore diameter and .043 inch (1.09mm) compressed thickness, making it ideal for performance engine builds requiring precise compression control.

Key Features:

• 84.5mm bore diameter for increased displacement applications
• .043 inch compressed thickness for compression tuning flexibility
• Solid copper construction provides superior heat dissipation and conformability
• No steam holes configuration for specific application requirements
• Designed for Honda Civic and CRX with Integra VTEC cylinder head conversions
• Excellent for high-performance and turbocharged applications

Copper head gaskets are favored in racing and high-output engine applications due to their ability to conform to imperfect sealing surfaces and withstand extreme cylinder pressures. The solid copper material offers exceptional thermal conductivity, helping to transfer heat away from the combustion chamber more efficiently than traditional multi-layer steel gaskets. This gasket is engineered without steam holes, which is critical for certain engine configurations where steam hole alignment differs from OEM specifications.
