Manley Mitsubishi Evo VIII/IX 4G63/4G63T 85mm Bore 8.5:1 Comp Ratio -12.1.0cc Dish T/T Piston Set

Starting with 2618 alloy forgings, these Manley pistons are built for serious performance in your Mitsubishi Evo VIII or IX with the 4G63 or 4G63T engine. The 85mm bore size is a common upgrade for rebuilding or modifying these popular engines, and the 8.5:1 compression ratio with a -12.1.0cc dish is designed to work well with forced induction setups, offering a good balance for power and reliability.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them run true and quiet while also being gentle on your cylinder walls, which is crucial for longevity, especially when you're pushing the limits. The ring lands and grooves are machined to strict standards, which is key for getting a solid seal from your piston rings. A good ring seal means better compression, more power, and less oil getting into the combustion chamber. They also use tool steel wrist pins for added strength, capable of handling the stresses of a performance engine.

These pistons are a popular choice among professional engine builders for a reason. They offer a well-built foundation for a high-output engine. When you're rebuilding the heart of your Evo, starting with quality components like these Manley pistons sets you up for success. Keep in mind these are not CARB approved and cannot be shipped to California.
