About this part

Product Details

Forged from 2618 aluminum, this JE Pistons single piston is built for the demands of performance Subaru EJ Series engines. It features an inverted dome/dish design with a 9.50:1 compression ratio and a 99.52 mm bore. This piston is designed specifically for the EJ Series engine, aiming for optimized performance and durability. The Forged Side Relief (FSR) design helps minimize friction and power loss by reducing skirt width, while also saving weight with a shorter wrist pin. Some applications may include a skirt coating to further reduce friction and wear, and an accumulator groove to help manage combustion gas pressure for improved ring seal and consistent power delivery. This piston is made 100% in the USA and includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This piston is intended for use in Subaru EJ257 engines. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
