It’s been yrs in the making! This product was stillborn collecting dust on the back shelves of VR until customer demand and time caught back up to its need for further development for production.
After hundreds of hours on the flow bench comparing the VR design to the very best the competition had to offer, we are proud to present the VR power duct for the C5 corvette.
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!
We only flow through the Throttlebody, 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, 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!

pain to install this item tokk around 6 hours to install due to not having corect size & length of hose to do project. Instructions showing moving mass air flow cencer never did work I spent hours on phone with seller & manufacturer figuring out what was wrong with fitment. After getting corect parts for unit it was still a pain in rear to custom cut & fit unit on car i allmost gave up & sent item back but lots of cussing & determination i finally got item to work. it looks good on car & hood shuts fine i…
This is basically the same thing as the stock air … This is basically the same thing as the stock air duct. Not worth$100 by any means. Sending it back for a refund.
Works wel Was nervous about fitment apparently earlier versions had mine fit great noticeable improvement not sure of any hp gains but my butt dyno seems to think so mine is on an aftermarket twin filter intake
