Forged Piston Kit by OS Giken F6A

Product Features

⚫︎It has been created by refining its "high sealing performance" that does not let combustion pressure escape, "low friction" that allows smooth up and down movement, and "high durability" that allows piston heat to escape.

⚫︎The top land has three grooves, and the labyrinth effect also enhances sealing, making this a forged piston that is suitable for high revolutions and high power output. (Recommended piston clearance: 0.05mm)
