Wiseco Volkswagen KR/PL 1.8L 16V 81.50mm Bore 8.8:1 CR -1cc Dome Piston Set

If you're rebuilding the engine in your 1987-1989 Volkswagen Golf with the 1.8L 16V engine, this set of four forged pistons from Wiseco is built for demanding performance applications. These pistons are designed to handle heavy to severe duty use, making them a solid choice for racers and serious builders looking to push their engines further.

Crafted in the USA from 2618 aluminum, these pistons offer improved tensile strength over stock. They feature precision ring grooves, anti-detonation features, and additional ring seal improvements to ensure reliable performance under pressure. The fully machined crown and forced pin oiling further contribute to their durability and longevity. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly.

This set includes pistons with an 81.50mm bore and a -1cc dome, resulting in a compression ratio of 8.8:1. The compression height is 32.65mm, and they use a 0.787-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
