CP Piston & Ring Set Mitsubishi 4G63 2G/Evo 8/9 - Bore 86mm - Size +1.0mm - Stroke 94 - CR 9.0

If you're rebuilding the engine in your Mitsubishi 4G63 2nd Gen or Evo 8/9, especially for a performance build, a solid set of pistons is crucial. These CP Pistons are forged from high-strength aluminum, making them well-suited for the demands of a performance 4G63 engine. They're designed to handle increased boost and higher RPMs compared to stock cast pistons.

This specific set is for an 86mm bore and is sized at +1.0mm, meaning it's intended for an engine that has been bored out to accommodate this larger size. The 94mm stroke and 9.0:1 compression ratio are key specs to consider for your build's intended power band and fuel requirements. Forged pistons like these offer improved durability and resistance to detonation, which is essential when pushing an engine beyond its original design limits. They are a popular choice for enthusiasts looking to maximize the potential of the 4G63 platform.

This set includes the pistons and rings, ready for installation. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to ensure these specifications align with your specific engine build goals.
