JE Pistons SUB WRX EJ205 92.5mm Bore CR 9.5 KIT - Single Piston (Right Side)

Forged from 2618 aluminum, this JE Pistons single piston is built for the demands of performance Subaru EJ205 engines. The 92.5mm bore and 9.5:1 compression ratio are designed to optimize power and durability for specific engine applications, whether you're hitting the track or pushing your car on the street.

JE Pistons applies over 75 years of experience to their forged pistons, with this one being machined 100% in the USA. It features a proprietary Forged Side Relief (FSR) design that helps minimize friction and power loss by using a reduced skirt width. Depending on the application, a skirt coating can further reduce friction and wear on the cylinder walls, while also quieting down operation. An accumulator groove, also application-dependent, can help manage combustion gas pressure to reduce ring flutter and improve seal for consistent power delivery.

This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation. Please note that this piston is not CARB approved and cannot be shipped to California.
