JE Pistons Subaru EJ Series 99.52 mm Bore 1.209 In CH -7.00 CC - Single Right Piston

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in your Subaru EJ Series engine. This specific piston is designed for a 99.52 mm bore and features an inverted dome/dish with a -7.00 CC volume, aiming for a 9.50:1 compression ratio. JE Pistons has been making forged pistons for over 75 years, and they engineer these for specific engines and racing applications to give you the best mix of durability and performance.

The design includes a proprietary Forged Side Relief (FSR) forging, which helps reduce friction and power loss by using a narrower skirt width. Some applications also get a skirt coating to further cut down on friction and wear, while also making the engine run a bit quieter. An accumulator groove is included in some designs to help manage combustion gas pressure, which can prevent ring flutter and improve the seal for consistent power delivery. These pistons are made 100% in the USA and come with high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This is a single right piston, so you'll need to order the correct quantity and configuration for your specific EJ257 engine build. Please note that this part is not CARB approved and cannot be shipped to California.
