Wiseco Audi RS2 2.2L 20V 5 cyl Bore (83mm) - CR (7.2:1) Pistons

Wiseco is well-known for making strong internal engine components, especially for performance applications. If you're rebuilding the engine in your 1992-1994 Audi S4 or your 1995 S6, these forged pistons are built to handle serious power. They are designed for the ADU 2.2L 20V engine, with a bore size of 83mm and a compression ratio of 7.2:1, making them suitable for builds that demand heavy to severe duty performance.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for durability under high stress. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The fully machined crown and forced pin oiling are also notable details for performance builds. Additionally, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set includes five pistons, the correct amount for your 5-cylinder Audi engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful rebuild, always refer to the manufacturer's installation instructions for specific details on fitting and assembly.
