JE Pistons SUB WRX EJ205 92mm Bore CR 9.5 KIT - Single Left

If you're rebuilding the engine in your Subaru WRX with the EJ205 engine, you're likely looking for pistons that can handle the demands of performance driving. These JE Pistons are forged from 2618 aluminum, a strong material chosen for its high tensile strength, making them well-suited for high-demand applications where durability is key. They are designed specifically for the EJ205 engine to offer optimized performance and longevity.

JE Pistons uses a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt. This design also contributes to weight savings. Depending on the specific application, these pistons may also feature a skirt coating to further reduce friction and wear on the cylinder walls, leading to quieter operation. An accumulator groove can also be included to help manage combustion gas pressure, which improves ring seal and ensures consistent power delivery. This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, and everything is made 100% in the USA.
