JE Pistons PORSCHE 3.3L DM KIT - Single

If you're working on a Porsche 3.3L air-cooled six-cylinder engine, this single forged piston from JE Pistons is built to handle the demands of performance applications. JE Pistons has been making forged pistons for over 75 years, and they engineer these specifically for each engine to give you the best combination of durability and performance.

This piston is forged in the USA from 2618 aluminum, which gives it the high tensile strength needed for high-demand use. It features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. Some applications also include a skirt coating to further reduce friction and wear, and an accumulator groove to help reduce combustion gas pressure, which improves ring seal for consistent power. This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This piston is designed for a 3.858 inch bore with a dome top and a compression ratio of 8.50:1. Please note that this part is not CARB approved and cannot be shipped to California.
