Discover the ultimate in engine performance with the Subaru WRX Engine Piston Set by Manley Performance. This extreme duty set is designed for the 2004 Subaru WRX and features a 100.0mm bore with a +.50mm size and an 8.5:1 dish, ensuring optimal power and efficiency for your vehicle.

The Manley Subaru WRX Engine Piston Set is engineered using premium 2618 alloy forgings, renowned for their exceptional strength and durability. These pistons are built to withstand extreme conditions while delivering consistent performance. With chrome moly wrist pins as a standard inclusion, you are assured of robust support under high-speed and high-torque situations. Furthermore, for select SKUs, we offer upgrades to 9310 and Turbo Tuff/DLC alloy wrist pins, enhancing durability.

For maximum power and efficiency, our pistons feature exacting ring lands and grooves. These precise standards ensure enhanced ring seal, resulting in improved power output. The cam and barrel (skirt) profiles not only generate significant power but also protect your cylinder walls from wear and tear. Thanks to Manley’s unique fixturing process, the skirt turning and ring groove machining are accomplished in a single operation, guaranteeing perfect ring groove to skirt squareness.
