COMETIC Gasket Set - 78 mm - Honda C3133-EST

Factory gaskets can't handle the cylinder pressures generated by high-output 4-stroke engines, whether naturally aspirated or boosted. The COMETIC C3133-EST gasket set uses multi-layered steel construction with Extreme Sealing Technology (EST) to maintain consistent compression sealing across the bore while managing heat more effectively than conventional gaskets. This means better ring seal, more reliable power delivery, and fewer comebacks due to gasket failure.

The MLS (multi-layer steel) head gasket design distributes torque load evenly across the sealing surface, reducing bore distortion and hot spots that compromise gasket integrity. Combined with embossed stainless steel construction and proprietary Viton rubber coating, this kit delivers the durability required for serious racing and high-performance applications.
