NOS offers supercharger injector plates and nitrous systems with black anodized polished aluminum plates, along with black nozzles, hardware, and bottles to give you a modern look to our popular 6-71/8-71 Supercharger nitrous lineup. Superchargers not only create more horsepower, but they also add unwanted engine heat. These NOS supercharger nitrous oxide systems can remedy that problem and increase power output at the same time. The nitrous is injected into the engine at -127 degrees F and mixes with the incoming air, reducing intake temperatures by up to 75 degrees F. The result is a denser intake charge and an increase in torque and horsepower of up to 30 to 40 percent over the entire power band! Plus, the nitrous can be injected at lower rpm--before the engine is at full boost--eliminating lag time and providing instantaneous power gains. Designed for 6-71 or 8-71 Roots style superchargers
