JE Pistons SUB WRX EJ205 79mm STR 92mm Bore CR 9.5 KIT Set of 4 Pistons

If you're rebuilding the engine in your Subaru WRX with the EJ205 engine, especially for performance applications, a solid set of pistons is crucial. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of a performance engine. They are designed specifically for the EJ205, aiming for optimized performance and durability.

JE Pistons brings over 75 years of experience to these components, and they're manufactured entirely in the USA. You'll find their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also help quiet down operation.

This kit includes everything you need to get your engine rebuilt: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
