Manley 98+ Subaru WRX (EJ205) STD Stroke 93mm +1mm Bore 8.5:1 Dish Piston Set with Rings

Starting with the 2618 alloy forgings, these Manley pistons are built for serious work inside your 2002-2005 Subaru Impreza WRX. The EJ205 engine in these cars can benefit greatly from a well-built set of pistons, especially if you're pushing more power than stock. These are designed to handle that extra stress, giving you a solid foundation for your engine build.

Manley uses proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, which is key for longevity and making power. They also pay close attention to the ring lands and grooves, ensuring a tight seal for better compression and more efficient combustion. You'll find that the included wrist pins are made from Chrome Moly, adding to the overall strength and reliability of the assembly. The unique machining process Manley uses ensures the ring grooves are perfectly square to the skirt, which is a detail that matters for consistent performance.

This set is specifically for the 93mm bore size, which is a +1mm overbore from the standard size. It also features an 8.5:1 compression ratio dish piston, making it a good choice for boosted applications where you need to control detonation. Remember, these are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's installation instructions for specific details on fitting these pistons into your engine.
