JE Pistons ACURA K20 10:1 KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set of four pistons is designed specifically for the Acura K20 engine, featuring a 10.00:1 compression ratio and a 3.465-inch bore. JE Pistons brings over 75 years of experience to their forged piston designs, ensuring durability and performance for racing and high-performance street use.

JE Pistons utilizes a proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce pressure from combustion gases, which helps improve ring seal and maintain consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every component in this kit is made 100% in the USA, including high-quality wrist pins, locks, and JE Pro Seal premium piston rings. This ensures you're getting a well-built set ready for demanding use. Please note that this kit is not CARB approved and cannot be shipped to California.
