The APR Stage III B7 RS4 4.2L FSI V8 Supercharger System transforms the RS4 to supercar status by delivering a 3.9 second 0-60 time on a blazing hot 97F summer day. This was all made possible by simply upgrading the engine with the APR Stage III Supercharger system on regular 93 octane pump fuel. The exhaust, intake and wheels are stock and the tires are normal street tires. The vehicle also has a full interior.
The 0-60 time was tested and recorded using a Racelogic P-Box.
