Product Details
Forged from 2618 aluminum, this JE Pistons single piston is built for high-demand performance applications. It's designed specifically for the Subaru WRX EJ205 engine, featuring a 92.5mm bore and a 9.5:1 compression ratio with a dome top. This piston is made 100% in the USA, ensuring robust construction for serious engine builds.
JE Pistons incorporates a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. Depending on the specific application, a skirt coating may be applied to further reduce friction and wear on the cylinder walls, while also contributing to quieter operation. An accumulator groove can also be included to help manage combustion gas pressure, reducing ring flutter and improving the piston ring seal for more consistent power delivery.
This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Please note that this part is not CARB approved and cannot be shipped to California.
