''Make more horsepower and improve overall performance and fuel mileage from your high dollar engine! Constructed of 7075 Aluminum and CNC cut, Innovative Designs Velocity Venturi's have no match! Velocity venturi's have been designed using technology taken from aircraft jet engine technology and provide a substantial increase in air flow improvement over all stock factory venturi's. This means more usable horsepower and the ability to hold a better tune for maximum performance. Velocity venturi's improve bottom end response with out sacrificing top end power. These inserts are complete with supplied o-rings, and are anodized and notched for easy removal.

The new design is 3mm taller than the standard Velocity Venturi's. This provides improved air flow, for even greater fuel economy and low end response. This venturi features the same high flow design as the standard Velocity Venturi's and is notched for easy removal.''

Has anyone try this venturi and he notice any change?better fuel consumption or better tuning and engine breathing ?
