A new and exciting design from Zodiac are these Voronoi HP velocity stacks. Contrary to most other velocity stacks the Voronoi has a true air filter element incorporated in the 4 (10 cm) diameter throat. Consequently the Voronoi not only looks great and increases engine power, it also prevents road grime and dirt from entering your expensive engine. These velocity stacks are made from billet aluminum and CNC precision cut, then hand polished and chromed or black anodized to perfection. The black version is then raw cut to enhance its appearance. Available in straight or aggresive looking “tilt forward” design that comes with a cast elbow in a matching chrome or black finish. We will accept your request at our earliest opportunity.
