Stage III Retrofit Coolant Kit
Audi RS4 4.2l Stage III
Supercharger System
APRs Engineering Teams are pleased to present our first
iteration of the Audi 4.2l V8 FSI
supercharger application. Producing over 570hp and 510 ft-lbs of
torque, APRs RS4 Stage III propels one of
Audis most prestigious performance vehicles to new levels of
acceleration and performance.
Applying forced induction to a normally aspirated production
engine is no simple task and APRs Engineering Teams understand that
new innovations, processes and components must be incorporated into
the design to insure OEM reliability and drivability
while producing incredible performance results. Within APRs Stage
III, you will find more components and higher quality
parts at every comparison than with any of the competing products
currently available. The goal of APRs design was not merely fitment
and operation but consideration of the long term effects of such a
dramatic power increase and the overall reliability of the vehicle.
Extra steps must be taken to insure Performance Without
Compromise.
Not only will RS4s equipped with APRs Stage III
produce blistering increases in wide open throttle acceleration,
daily driving is greatly improved with increased torque and
horsepower available in even the lowest rpms of the power band.
Less downshifting for passing and greater rates of acceleration at
all points result in a driving characteristic of pure enjoyment in
all situations. Both Drag Racing and Road Racing demands are taken
into consideration during the design and calibration process in
order to provide a well rounded solution for all enthusiasts.
