CP Piston & Ring Set Mitsubishi 2nd Gen 4G63 Bore (85.5mm) - Size (+0.5mm) 9:1 CR - SINGLE

CP Pistons is well-known for making strong, reliable internal engine components. This forged piston and ring set is built for the Mitsubishi 2nd Gen 4G63 engine, specifically designed for builds that need a bit more than stock. It features a bore size of 85.5mm, which is a +0.5mm overbore from the factory specification, and a 9:1 compression ratio. This setup is ideal for enthusiasts looking to rebuild or enhance their engine with well-built internals that can handle increased stress.

Forged pistons like these are made from a solid block of aluminum that's heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is crucial for engines that see higher cylinder pressures, whether from forced induction or higher compression tunes. The included rings are designed to seal properly against the cylinder wall, ensuring good compression and oil control. This set is sold as a single piston and ring package, so be sure to order the correct quantity for your engine.

Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
