CP Piston & Ring for Mitsubishi Evo 8/9 - Bore (85.0mm) - Size (Std) - CR (9.5) - SINGLE PISTON

CP Pistons is well-known for making strong internal engine components, and this forged piston for the Mitsubishi Evo 8 and 9 is a prime example. This is a single piston designed to replace one of your stock pistons, featuring a standard 85.0mm bore and a 9.5:1 compression ratio. If you're rebuilding the top end of your Evo's engine, a well-built forged piston like this can handle more stress than a cast piston.

Forged pistons start as a solid block of aluminum that's heated and hammered into shape, making them inherently stronger and more resistant to detonation and fatigue. This particular piston is built to the standard bore size, so it's a direct replacement for a stock piston if you're just replacing one or building a matching set. The 9.5:1 compression ratio is a common choice for naturally aspirated or mildly boosted applications, offering a good balance between power and drivability.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. If you're working on a performance build for your Evo, this piston offers a solid foundation for the engine's internals.
