Description

Part #: 23004B

Exact fit A, B or C pistons match your cylinder bore perfectly to maximize power and performance, while reducing blow-by and oil consumption. All piston kits include piston, rings, wrist pin and circlips required.

MIA's Description

The Vertex Pistons 23004B is a cast replica piston designed for specific engine applications. It features a standard compression ratio and a hi-tech Molybdenum Disulphite coating on the piston skirts. This coating aids in faster break-in times and extends the piston's lifespan. The piston also undergoes a T-5 hardening and tempering cycle for increased durability.
