COMETIC Gasket Set - 103 mm - Yamaha C3142-EST

A quality gasket set is foundational to engine reliability and performance—especially when you're building or rebuilding a high-output 4-stroke. The COMETIC C3142-EST Gasket Set delivers the sealing integrity and thermal management required to handle elevated cylinder pressures, whether you're running naturally aspirated or forced induction. With multi-layered steel construction and proprietary Viton-based coatings, this kit minimizes bore distortion and maximizes piston ring seal for consistent power delivery.

COMETIC's Extreme Sealing Technology (EST) is engineered for the demands of modern high-horsepower engines. The embossed stainless steel design promotes even torque load distribution, while advanced heat dissipation eliminates hot spots that compromise gasket longevity. This is the kind of precision component that separates a solid rebuild from one that leaves performance on the table.
