Product Details

The Cometic C4543-056 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for the Nissan SR20DET turbocharged engine found in 1990-1994 applications. This precision-manufactured gasket features an 87.5mm bore diameter and .056" (1.42mm) compressed thickness, making it ideal for high-performance builds and AWD configurations.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 87.5mm bore diameter for optimal combustion chamber sealing
  • .056" compressed gasket thickness
  • Designed for 1990-1994 Nissan SR20DET turbocharged engines
  • Compatible with AWD applications

Why MLS Technology:

  • Provides excellent sealing under extreme cylinder pressures
  • Handles thermal expansion better than composite gaskets
  • Resists blown gaskets in high-boost turbocharged applications
  • Allows for minor surface imperfections without compromising seal integrity

Cometic's MLS head gaskets are a trusted choice for engine builders and performance enthusiasts seeking reliable sealing in demanding conditions. The .056" thickness helps maintain proper compression ratios while providing the durability needed for modified SR20DET engines running elevated boost levels.
