THIS IS NOT JUST ANOTHER POWER DUCT!
The VR was engineered for stock to high horsepower cars of 500-700 rear wheel HP!
This unit can be used with the VR B2 System, Blackwing, K&N and many more and use it you should, because the VR out flowed the very best by over 15% @ 28 inches of water
and 20% @10 inches through the throttle body!
The key to its performance is in its Patent Pending reverse venturi design with integrated rear air horn. It’s not about making a bigger hole for airflow, its about streamlining the existing airflow
while increasing the overall volume delivered at the highest possible velocity at each RPM level THROUGH THE MAF AND THROTTLE BODY!
