Wiseco Volks 2.0 9A 16v Dome +4cc Nitrous 83mm Piston Shelf Stock Kit

If you're rebuilding the engine in your 1990-1992 Volkswagen Golf or Jetta for serious performance, this Wiseco forged piston set is built to handle the stress. These pistons are specifically designed for heavy to severe duty race applications, meaning they're made to withstand the demands of high-performance engines, including those running nitrous oxide. The set includes four pistons, each with an 83mm bore, ready to be installed in your 9A engine. Wiseco engineers these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for pistons operating under extreme conditions.

You'll find precision in every detail, from the carefully machined crown to the advanced ring grooves designed for better sealing and anti-detonation. They also feature forced pin oiling to ensure the wrist pins stay well-lubricated, reducing wear. A notable feature is the ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. This is a well-built set intended for builders who are pushing their engines to the limit and need components they can rely on for durability and performance.

This kit is designed as a shelf stock replacement for the 9A engine, simplifying installation for experienced builders. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation and tuning.
