This JE Pistons single replacement piston for Volkswagen and Audi 1.8T 20-valve engines using 20mm wrist pins brings forged 2618 aluminum construction to a performance engine rebuild or replacement assembly. Its full round skirt design provides a conventional piston profile with crown geometry and dimensions developed for the specific engine application. The application-specific crown, ring grooves, and pin dimensions provide the detailed configuration needed when matching an individual piston to an existing JE setup. Precision machining and decades of JE motorsport experience support a durable component for demanding engine use. Supplied as one piston with rings included, this replacement provides the specified bore size and crown volume without requiring the purchase of a full four-piston kit.
