Manley 08+ Mitsubishi 4B11T 86mm STD -5cc Dome 9.0:1 CR Platinum Series Piston Set w/ Rings

If you're rebuilding the engine in your 2008 and up Mitsubishi 4B11T, a solid set of pistons is crucial for getting the power and reliability you need. This Platinum Series piston set from Manley is built to handle the demands of a performance engine build.

These pistons are forged from domestic 2618 alloy, which is known for its strength and ability to perform under high stress. Manley uses proven cam and barrel skirt profiles that help generate power while also being easy on your cylinder walls. The ring lands and grooves are machined to very precise standards, which helps ensure a good seal from your piston rings, leading to more efficient combustion and better power output. This set includes tool steel wrist pins for added durability, and the pistons themselves have a -5cc dome shape, resulting in a 9.0:1 compression ratio when installed in your 4B11T.

Manley's manufacturing process includes unique fixturing that allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which is important for proper ring function. This set comes complete with rings, ready for installation by a professional engine builder.
