For use in Multi-Stage Direct Port Nitrous or Fuel applications


Quality distribution blocks are a necessity for today's multi-stage, high powered Nitrous systems. The engineers at NOS have taken the tried-and-true showerhead design and turned it into a low profile, user friendly design. The parallel inlet/outlet design allows for a much more compact installation of the Nitrous solenoid feed lines. The internal passages are profiled to maximize flow and minimize pressure drop across the distribution block. For the best flowing, most compact showerhead distribution blocks, look for the NOS Logo.
