Wiseco Volks 2.0 9A 16v Dome +4cc Nitrous 83.5 Piston Shelf Stock Kit

If you're rebuilding the engine in your 1990-1992 Volkswagen Golf for serious performance, this Wiseco piston set is built to handle the demands. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength over cast aluminum. This makes them a solid choice for heavy or severe duty applications where reliability is key.

Wiseco has packed these pistons with features for racers. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for both power and longevity. The fully machined crown is ready for your build, and they even come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, so your engine can run smoother and longer under stress.

This kit includes four pistons, each with a dome volume of +4cc, designed for a 9A engine with a 16-valve head. The bore size is 83.50 mm, and the compression height is 29.768 mm, with a standard 0.7874-inch pin diameter. Keep in mind 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.
