Manley Mitsubishi Evo VIII/IX 4G63/4G63T 86mm Bore 8.5:1 Comp Ratio -12.1cc Dish T/T Piston Set

If you're rebuilding the engine in your Mitsubishi Evo VIII or IX, especially for a performance build, a solid set of pistons is where you start. This set from Manley Performance is built for the 4G63 and 4G63T engines, featuring an 86mm bore and an 8.5:1 compression ratio. This compression ratio is a good balance for many modified setups, offering flexibility for different tuning goals.

Manley uses their signature 2618 alloy forgings for these pistons, which are known for being strong and reliable under demanding conditions. They also come with tool steel wrist pins, which are tough enough for serious street or track use. The pistons have proven cam and barrel skirt profiles designed to make good power while also being easy on your cylinder walls, which helps with longevity. Manley also pays close attention to the ring lands and grooves, machining them to strict standards to ensure a good seal and prevent power loss.

This piston set is designed to fit right into your Evo's engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine, these Manley pistons are a well-built option that many professional builders trust.
