120370 Black Voronoi Velocity Stack and Air Cleaner Straight

This Voronoi HP velocity stack by Zodiac features a 4" diameter throat with an integrated air filter element, offering a unique blend of performance and engine protection. CNC machined from billet aluminum, it is hand-polished and available in chrome or black anodized finishes with raw-cut highlights. The design is engineered to increase engine power by optimizing air velocity while the internal filter prevents road grime from entering the intake. Available in straight or aggressive tilt-forward styles, this stack requires a separate adapter bracket kit for mounting. It provides a clean, custom look for Harley-Davidson motorcycles without the risks associated with unfiltered velocity stacks.
