JE Pistons SUB WRX EJ205 79mm STR 92mm Bore CR 8.5 KIT Set of 4 Pistons

This JE Pistons kit gives you a complete set of four forged pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings. These pistons are built for performance applications, specifically designed for the Subaru WRX EJ205 engine. They feature a 92mm bore and a compression ratio of 8.5:1, making them a solid choice for engine builds where durability and power are key.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. The pistons are forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for demanding performance use. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and preventing flutter, as well as a skirt coating to reduce friction and wear while quieting operation.

Because these pistons are engineered specifically for the EJ205 engine, you can expect optimized performance and durability. This kit is made 100% in the USA, ensuring a well-built product ready for the track or street.
