Wiseco VW 1.8L 8V 82.50 mm Bore 39.50 mm CH -16.50 CC Piston Set

These Wiseco pistons are forged from 2618 aluminum right here in the USA, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They're specifically made for Volkswagen's 1.8L 8-valve engines and come with an 82.50 mm bore size. This set is built for serious racers and builders who need components that can handle heavy to severe duty performance applications.

You'll find precision machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal, meaning better compression and more consistent power. The fully machined crown ensures accuracy, and they even feature forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making for a smoother running and more durable engine build. These are designed to remove limits for those serious about their race builds.

This set includes four pistons, each with a 39.50 mm compression height and a 0.866-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. If you're building a high-performance VW engine, these pistons are a solid option to consider for the core of your build.
