Manley 08+ Mitsubishi Evo X 4B11T 94mm Stroker 86.0mm Bore 9.0:1 Dish Extm Duty Piston Set w/ Rings

This Manley piston set includes forged pistons, premium chrome moly wrist pins, and piston rings. These are designed for the 2008 and later Mitsubishi Evolution X with the 4B11T engine, featuring a 94mm stroke, 86.0mm bore, and a 9.0:1 compression ratio with a dish top. They are built for extreme duty applications, meaning they can handle the demands of high-performance engines.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their superior strength and ability to perform under stress. The pistons feature proven cam and barrel skirt profiles, designed to generate substantial power while also being gentle on your cylinder walls, which helps with longevity. Manley also pays close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal from your piston rings, leading to more efficient power delivery. Their unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring the ring groove stays perfectly square to the skirt for optimal performance.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your 4B11T engine and looking for a well-built set of forged pistons that can handle serious power, this Manley set is a solid option.
