Manley 08+ Mitsubishi Evo X (4B11T) 86.5mm +.5mm Oversize Bore 9.0:1 Dish Piston Set with Rings

If you're rebuilding the engine in your 2008-2014 Mitsubishi Lancer, especially if you're aiming for more power or need to replace worn components, a solid set of forged pistons is crucial. This set from Manley Performance is built to handle the demands of a performance engine, offering a reliable foundation for your build. They feature an 86.5mm bore with a +.5mm oversize, meaning they are 0.020 inches larger than stock, and a 9.0:1 compression dish, which is a common target for boosted applications.

Manley uses their signature 2618 alloy forgings, which are known for being strong and performing well under high stress. These pistons also come with tool steel wrist pins for added durability, and the skirt profiles are designed to be gentle on the cylinder walls while still generating power. The ring lands and grooves are machined to strict standards to ensure a good seal, which is key for both power and efficiency. Manley's manufacturing process ensures the ring grooves are square to the skirt, contributing to overall engine health and performance.

This piston set includes the necessary rings to complete the installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful rebuild, always refer to the manufacturer's detailed installation instructions and ensure all related components are within spec.
