07-15 KAWASAKI VN900C: Cobra Air Cleaner Kit - Cross (BLACK) Take the internal elements from the PowrFlo Air Intake and replace the outside cover with trimmed down, edge-cut frames and you have Cobra's Air Cleaner Kits. The frames are laser-cut steel, polished and powder coated black. The Cobra C-over-V logo is laser cut into the top rear leg of the frame. Flows better than stock or competing units in large part because of Cobra's unique internal venturi design of the filter. Optimizes overall performance.
