Wiseco Audi RS2 2.2L 20V 5 Cylinder 82mm Bore 86.40 Stroke CR 8.0:1 Pro Tru Sport Series Piston

If you're rebuilding the engine in your 1992-1994 Audi S4, these Wiseco Pro Tru Sport Series pistons are a solid choice for a high-performance build. Designed for the demanding Audi ADU 2.2L 20V engine, these pistons are forged from 2618 aluminum right here in the USA, giving them improved tensile strength for serious power applications.

Wiseco machines these pistons with precision ring grooves, anti-detonation features, and enhanced ring seal technology to ensure they can handle heavy to severe duty use. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep things running quieter. The fully machined crown and forced pin oiling further contribute to their durability and performance under pressure. This set includes five pistons, ready to be installed in your 82mm bore engine.

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 the necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
