Power, Drivability, Reliability: these three words sum up our Audi 2.7T K04 Stage III kit. APR's unique approach to product development brings together a product with the level of refinement that this car deserves.

APR has a history of developing high-quality turbocharger upgrade kits. Our 2.7T Stage III upgrade system continues this tradition. This product uses RS4 components, APR-designed components, and of course, APR-engineered engine management software calibrations.
