The Cometic GM LHU/LNF Gen-2 ECOTEC .042in MLX Cylinder Head Gasket - 88mm Bore - C15256-042 is a precision-engineered head gasket with a 88mm bore and .042" compressed thickness.

The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring MLX Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers for superior sealing under extreme cylinder pressures and temperatures. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.

  • Material: MLX Multi-Layer Steel (MLS)
  • Bore Size: 88mm
  • Thickness: .042" compressed
  • Part Number: C15256-042

Verified fitment: Buick Regal (2011–2013); Chevrolet HHR (2010).
