About this part

Product Details

This is the Manley Platinum Series Piston Set, part number 614105C-4. Inside this box, you'll find a complete set of four forged pistons, each measuring 86.5mm in bore diameter and designed as a +0.5mm oversize replacement. These pistons feature a +2cc dome volume, which is important for setting your compression ratio. They also come with premium chrome moly wrist pins and a set of piston rings, ready for installation into your Mitsubishi 4B11 engine.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its strength and ability to handle high performance demands. The pistons are shaped with proven cam and barrel skirt profiles, which help generate power efficiently while also being considerate of your cylinder walls during operation. The ring lands and grooves are machined to very strict standards, which is key for getting a good seal from your piston rings and maximizing power output. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in the same operation, ensuring they are perfectly square to each other for optimal ring seal.

This set is a solid option for anyone rebuilding or upgrading their Mitsubishi 4B11 engine, especially if you're aiming for improved performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
