Nitrous Pro Flow direct port nitrous systems offer maximum horsepower capabilities from 50 to 250 hp. At the heart of these systems is the Nitrous Pro Flow conical discharge dry nozzle, which promotes the expansion of nitrous in a conical pattern upon exiting the nozzle. This helps to more completely fill the intake tract, leading to better distribution from cylinder to cylinder. They include high-flow nitrous solenoids, a nitrous purge solenoid, stainless steel hard lines, and an equalizer distribution block, which provide the best possible distribution of nitrous, while maximizing flow and preventing nitrous phase change. If you're looking for serious horsepower out of your nitrous system, Nitrous Pro Flow direct port nitrous systems are your solution.
