CP Piston & Ring for Mitsubishi 4G63 2G/Evo 8/9 -Bore (86.0mm)-Size (+1.0mm)-Stroke (100)- *SINGLE*

If you're rebuilding the engine in your Mitsubishi 4G63 2G, Evo 8, or Evo 9, a strong set of pistons is crucial. These CP Pistons are forged from high-strength aluminum, making them well-built for demanding performance applications. They are designed to be a +1.0mm overbore, meaning they are 86.0mm in diameter, which is common when reconditioning a worn cylinder bore or increasing displacement slightly.

CP Pistons are known for their robust construction. The forging process creates a denser, stronger piston compared to cast aluminum, which helps them withstand higher cylinder pressures and temperatures. This particular piston is sold individually, so you'll need to order one for each cylinder in your 4G63 engine. The 100mm stroke specification is also noted for compatibility with your specific crankshaft setup.
