Wiseco W6602 Sport Compact MLS Cylinder Head Gasket 81.5mm .030in 3-Layer

The Wiseco W6602 is a Sport Compact Multi-Layer Steel (MLS) cylinder head gasket engineered for high-performance and forced-induction engine builds. Constructed from a high-pressure steel-laminate design, this 3-layer gasket is built to withstand the extreme shear forces generated between an aluminum cylinder head and an iron engine block.

Internal embossments within the gasket material expand under heat, forming a progressively tighter seal as combustion pressures and temperatures rise — making the W6602 especially well-suited for power-adder applications such as turbocharged, supercharged, and nitrous-equipped engines.
