About this part

Product Details

Manley Performance is well-known for building strong engine components, and their pistons are a popular choice among professional engine builders. This single piston is made for the 2015 and later Subaru WRX with the FA20F engine, featuring an 86mm standard bore and a 10:1 compression dish.

This piston is forged from domestic 2618 alloy, which offers superior strength and performance compared to cast aluminum. It includes a premium chrome moly wrist pin and features exacting ring lands and grooves to ensure a better ring seal and more power. The cam and barrel skirt profiles are designed to generate substantial power while also being gentle on the cylinder walls, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt.
