Cometic C4283-040 MLS Head Gasket for Nissan SR20 Engines

If you're diving into a performance build for your 1993-1996 Nissan S14 with the SR20DE or SR20DET engine, the Cometic C4283-040 MLS (Multi-Layer Steel) Head Gasket is a crucial upgrade you shouldn't overlook. Designed to handle the demands of high-output engines, this head gasket offers unmatched sealing performance without the need for additional sealants, making it a favorite among DIY mechanics and seasoned tuners alike.

Why Choose Cometic MLS Head Gaskets?

Cometic's MLS gaskets are engineered for both aluminum-to-aluminum and aluminum-to-cast iron applications, ensuring they can withstand the shearing forces that occur between these materials. The multi-layer design, consisting of several layers of stainless steel, provides enhanced strength and durability, allowing the gasket to rebound and resist corrosion over time.

Technical Specifications

  • Drive Type: RWD
  • Engine Block Configuration: 2 Additional Oil Holes
  • Engine Compatibility: Nissan SR20DE/SR20DET 2.0L 16v (1993-1996 S14)

Performance and Reliability

The outer layers of the gasket are embossed and coated on both sides with Viton, a high-performance flouroelastomer that can withstand temperatures up to 250°C (482°F). This makes it ideal for high-stress environments, ensuring that your engine maintains optimal performance even under extreme conditions.

Owners of the Nissan S14 with the SR20DET engine have reported excellent results after installing the Cometic C4283-040. One SR20DET owner mentioned, “After swapping to this gasket, I noticed a significant improvement in sealing, especially when pushing higher boost levels. No leaks and the engine runs smoother!”
