Description

The Manley Performance 612200CB-1 is a dish piston designed for Subaru WRX STI EJ257 engines. It features a 99.50mm Grade B bore size and is made from robust 2618 aluminum for durability. This piston includes an offset wrist pin design for quieter start-ups and moly-coated skirts to reduce friction.

Precision manufacturing with a "one fixturing" method ensures perfect ring groove to skirt squareness for maximum horsepower delivery. Enhanced oil control is provided by Napier style second rings and higher tension oil rings.
