4-Cylinder 75–400 HP Single-Stage Direct Port Nitrous Kit

The Cold Fusion Nitrous Pro Race 4-Cylinder Direct Port Nitrous Fogger Kit is a complete single-stage system engineered for racers who want serious nitrous capability without piecing together a system component by component.

Designed for 75–400 HP applications, this package brings together the major components required to build a professional direct-port nitrous system. From the Super High Flow 10 lb nitrous bottle to the direct-port fogger hardware, feed system, electrical controls, and jetting, this kit is built as a complete performance package.

At the intake, four 90° wet fogger nozzles provide individual cylinder delivery. One super power nitrous solenoid with a .078" orifice handles nitrous flow, while one small fuel solenoid with a .125" orifice provides the fuel side of the system. Two distribution blocks and eight ready-to-use stainless-steel tubes complete the direct-port plumbing.

The system also includes a 15-foot 4AN stainless-steel feedline, bottle brackets, 4AN bottle nut, and the electrical components needed to integrate the system into your vehicle.

On the control side, the kit includes wire, a 40-amp relay, wide-open-throttle kit, and toggle switch.

75 and 100 HP jet settings are included, giving you a defined starting point for tuning the system to your combination.
