Wiseco VW 1.8L 8V 81.50 mm Bore 39.50 mm CH -16.50 CC Piston Set

If you're building a high-performance Volkswagen 1.8L 8V engine, this set of forged pistons from Wiseco is designed to handle serious power. These pistons are made from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They're forged and machined right here in the USA, ensuring a well-built component for your build.

Wiseco has included several features to enhance performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is key for maintaining compression and preventing blow-by under high stress. The piston crown is fully machined for a clean combustion chamber, and they come with forced pin oiling to keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life even in severe duty applications.

This set includes four pistons, each with an 81.50 mm bore, a 39.50 mm compression height, and a 0.866-inch pin diameter. They are specifically designed for European 1.8L 8V VW applications. Keep in mind these are intended for racing and heavy-duty builds, and they are not CARB approved, so they cannot be shipped to California.
