The JE Pistons forged piston kit for Volkswagen and Audi 2.0T FSI engines using 20mm wrist pins gives your performance engine build a strong foundation for demanding street, track, and racing use. Manufactured in the USA from 2618 aluminum, these pistons combine durable construction with JE's application-specific engineering and decades of motorsport experience. The full round skirt design provides a conventional piston profile, with crown geometry and dimensions developed for the specific engine application. Precision machining carries that design through to the finished piston, giving engine builders a purposeful component for a performance short block. Supplied as a set of four with piston rings, this kit brings proven materials and carefully developed dimensions to your next engine build.
