Nitrous Oxide is often used for racing applications, due to it's power-increasing abilities which add extra oxygen to the air / fuel mixture, increasing combustion efficiency and power. 2015 Mustang nitrous kits are designed to set your S550 up for nitrous oxide applications with ease. Nitrous-charged vehicles operate at a maximum when equipped with other aftermarket performance bolt-ons, such as a Mustang Intake Manifold and Mustang Exhaust. Tie it all together with a proper Tuner to adjust ratios for the addition of air, fuel, and nitrous.
