Vararam VR Power Duct - 97-04 C5
Low Price Guarantee!
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!
Vararam only tests flow through the throttle body; test flowing a duct by itself tells you nothing of its true flow capabilities as delivered into the intake manifold. 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, it's 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!
