Manley 2015+ Subaru WRX FA20F 86.1mm +.1mm Bore 10:1 Dish Piston Single

This listing is for a single Manley Performance "Platinum Series" forged piston designed for the 2015 and later Subaru WRX with the FA20F engine. You get one piston, a premium chrome moly wrist pin, and the necessary rings to complete the piston installation. This piston features an 86.1mm bore size, which is +.1mm oversize from standard, and has a 10:1 compression dish. Manley uses domestic 2618 alloy forgings for superior strength, paired with proven cam and barrel skirt profiles that are effective at generating power while being gentle on your cylinder walls.

Manley's attention to detail extends to the exacting standards for ring lands and grooves, which helps ensure a better ring seal and more power. Their unique fixturing process allows for skirt turning and ring groove machining in a single operation, which guarantees the ring grooves are perfectly square to the skirt. This level of precision is why professional engine builders and tuners often choose Manley pistons for demanding builds.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's important to check manufacturer fitment data to confirm compatibility with your specific vehicle and engine build.
