Manley 98+ Subaru WRX (EJ205) 75mm STD Stroke 92.5mm +0.5mm Bore 8.5:1 Dish Piston Set with Rings

If you're rebuilding the engine in your 2002-2005 Subaru Impreza WRX, especially for a performance build, a solid set of pistons is crucial. These Manley Performance pistons are built to handle the demands of a tuned EJ205 engine. They feature a dish design that results in an 8.5:1 compression ratio, which is a common target for turbocharged applications where you need to manage detonation while still making good power.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The pistons also come with premium chrome moly wrist pins for added durability. Manley pays close attention to the details, ensuring the ring lands and grooves are machined to strict standards for a better seal, which translates to more power. Their unique cam and barrel skirt profiles are designed to be effective at generating power while also being kind to your cylinder walls during operation.

This set includes the pistons, rings, and wrist pins needed for a complete engine build. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
