Wiseco VW 1.8L 8V 81.00 mm Bore 39.50 mm CH -16.50 CC Piston Set

If you're building a serious performance Volkswagen 1.8L 8V engine, these forged pistons from Wiseco are a solid choice. They're designed for heavy-duty race applications where durability and consistent performance are critical. Wiseco machines these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for the demands of racing.

You'll find precision ring grooves, an anti-detonation groove, and other features to help improve ring seal, which is key for compression and engine health under high stress. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation, all important factors when you're pushing an engine hard. The fully machined crown and forced pin oiling further contribute to their ability to handle severe duty builds.

This set includes four pistons, each with an 81.00 mm bore, 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. For a robust engine build, these Wiseco pistons are a well-built component.
