Cometic C4950-050 MLX Cylinder Head Gasket - SR20DE/SR20DET 87mm 050

The Cometic C4950-050 is a high-performance Multi-Layer Steel (MLX) Cylinder Head Gasket engineered for Nissan SR20DE and SR20DET engines. Featuring an 87mm bore and 0.050" (1.27mm) compressed thickness, this gasket is built to withstand the extreme combustion pressures and temperatures found in both naturally aspirated and turbocharged SR20 applications, including high-boost forced induction builds.

Cometic's MLX gaskets are constructed from multiple layers of embossed stainless steel, providing superior sealing over OEM-style composite gaskets. The precision-embossed sealing beads conform tightly to cylinder head and block surfaces, delivering exceptional resistance to combustion gas blow-by, coolant leaks, and oil passage failure—even under aggressive power output.

Key Features:

• Construction: Multi-Layer Steel (MLX) — multiple embossed stainless steel layers for superior sealing
• Bore Size: 87mm — compatible with stock and mild overbore applications
• Compressed Thickness: 0.050" (1.27mm)
• Engine Compatibility: Nissan SR20DE and SR20DET (1989–2002), RWD applications
• Design: Precision-embossed sealing beads for fire ring and fluid passages
• Material: Stainless steel layers — corrosion and heat resistant
• Performance Rated: Suitable for forced induction and high-compression builds

The Cometic C4950-050 is an ideal solution for engine builders and performance enthusiasts refreshing or building a high-output SR20 powerplant. Whether used in a street build or a dedicated track application, this MLX head gasket delivers the reliability and sealing integrity demanded by performance engines.
