NOS Pro CrossHair Nitrous Plate Kit - Carbureted Applications

The NOS Pro Crosshair™ Nitrous Plate Kit is engineered for the serious racer demanding maximum power and consistent nitrous delivery. Built upon the proven Double Cross plate platform, the Crosshair™ design advances this time-tested architecture with significantly improved fuel and nitrous distribution — a critical advantage when working with today's complex intake manifold designs.

Capable of delivering 350+ horsepower gains, the Crosshair™ system features a unique double-cross, double-stack nitrous bar design that enhances atomization and ensures even distribution across the intake. The versatile setup can be run as a single-stage shot using both bars simultaneously, or configured as a two-stage system by activating one bar per stage — giving racers precise control over power delivery.
