The Cometic C4543-070 is a high-performance multi-layer steel (MLS) cylinder head gasket designed specifically for the Nissan SR20DET turbocharged engine found in 1990-1994 applications. This precision-engineered gasket features an 87.5mm bore diameter and a .070" (1.78mm) compressed thickness, making it ideal for both stock rebuilds and performance builds.

Key Features:

• Multi-layer steel (MLS) construction provides superior sealing and durability under high boost and extreme cylinder pressures
• 87.5mm bore diameter optimized for SR20DET engine specifications
• .070" compressed thickness for precise compression ratio tuning
• Engineered for AWD SR20DET applications from 1990-1994
• Exceeds OEM gasket performance in sealing and reliability
• Designed to withstand high heat and pressure associated with turbocharged engines
• Manufactured to Cometic's exacting quality standards for consistent performance

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that provide excellent recovery and conform to sealing surfaces. This design is particularly well-suited for turbocharged applications where cylinder pressure and temperature extremes demand superior gasket technology. The .070" thickness allows engine builders to fine-tune compression ratios when rebuilding or upgrading SR20DET engines.
