CP Piston & Ring Audi 2.0L/2.5L TSI 22mm Pin 83.5mm (+1.0mm Oversize) 9.5:1 - Set of 5

This set includes five forged pistons and their corresponding rings, designed for Audi 2.0L and 2.5L TSI engines. These pistons are 83.5mm in bore size, which is 1.0mm oversize from the standard bore, and feature a 22mm wrist pin. They are built to a 9.5:1 compression ratio, offering a balance between power and drivability for modified engines.

CP Pistons are known for their robust construction, and these are no exception. Forged from high-strength aluminum alloy, these pistons are designed to withstand the increased cylinder pressures and temperatures often found in performance applications. The 1.0mm oversize bore is crucial for rebuilding engines with worn cylinders or for those looking to increase displacement slightly. The included rings are specifically matched to these pistons to ensure a proper seal and optimal performance within the cylinder bore.

When rebuilding an engine with these pistons, it's important to ensure your machine shop is aware of the 1.0mm oversize specification for proper cylinder wall preparation. These pistons are intended for performance builds where the stock components may not be sufficient. Please note that this part is not CARB approved and cannot be shipped to California.
