THIS IS NOT JUST ANOTHER POWER DUCT! 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 theexisting airflow
while increasing the overall volume delivered at the highest possible velocity at each RPM level THROUGH THE MAF AND THROTTLE BODY!
Other features include:
1. Relocated MAF position-moves the MAF closer to the motor for a cleaner read, a must for any heads cam or stroker motor cars.
2. Superior quality in construction-a resin reinforced Crosslink Material that is set at a specified charge weight for strength and longevity, More expensive, yes, but 50% stronger than other systems.
3. Full adjustability-this enables the unit to fit a wide range of intake and filter combinations so you can use the VR power duct even if you don't have a VR-B2 system.
4. Positive clamp rings front and rear
