Wiseco K609M83 Sport Compact Forged Piston Set VW 2.0L ABA 8V 83mm 10.5:1

The Wiseco K609M83 is a shelf-stock forged piston kit engineered for the Volkswagen 2.0L ABA 8-valve engine. Designed for high-compression and turbo performance builds, this set delivers the precision, strength, and durability demanded by serious engine builders and racers alike.

Forged from 2618 aluminum alloy and machined in the USA, these pistons offer superior tensile strength and thermal resilience compared to cast or hypereutectic alternatives.
