Manley 03-06 Mitsubishi Evo 8/9 4G63T 87mm +2.0mm Bore 8.5/9.0:1 Dish Extreme Duty Piston - Single

If you're rebuilding the engine in your 2003-2006 Mitsubishi Evo 8 or 9, these single Extreme Duty pistons from Manley Performance are a solid option. They're designed for the 4G63T engine and feature an 87mm bore with a dish that results in a compression ratio of 8.5:1 or 9.0:1, depending on your cylinder head volume. These pistons are built to handle the demands of a performance engine build.

Manley uses domestic 2618 alloy forgings for these pistons, which offers superior strength compared to cast aluminum. They also feature proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls while still generating power. The ring lands and grooves are machined to strict standards to ensure a good seal, and they come with chrome moly wrist pins for added durability. Manley's unique manufacturing process ensures the ring grooves are square to the piston skirt, which is crucial for proper ring seal and performance.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Evo engine, these Manley pistons are a well-built choice.
