JE Pistons SUB STI EJ257 Block 100mm Bore CR 8.5 (Left Side) Single Piston

If you're rebuilding the engine in your Subaru EJ257, especially for performance applications, a strong set of pistons is key. This single forged piston from JE Pistons is built to handle the demands of a performance engine, offering improved durability and consistent power delivery. It's designed specifically for the EJ257 block, ensuring it works well with your engine's setup.

JE Pistons uses 2618 aluminum for these pistons, which gives them the high tensile strength needed when you're pushing your engine hard. They're forged and machined right here in the USA, meaning you're getting a well-built part with a focus on reliability. Features like the proprietary Forged Side Relief (FSR) design help minimize friction and save weight, while a skirt coating, if included for this specific application, further reduces wear and noise. This piston also comes with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have the essential components for a solid rebuild.

This listing is for a single left-side piston. Make sure to order the correct quantity and side for your specific engine build. Remember that this part is not CARB approved and cannot be shipped to California.
