Direct Nozzle Air-Intake Tube Nitrous Oxide

Nitrous Express (NX) Proton nitrous systems combine performance, durability, and value into compact and easy to mount nitrous/fuel modules. They lead the way in innovation and design, giving you the best off-the-shelf nitrous systems on the market today.

Standard NX Proton systems include jetting for 35, 50, 75, 100, 125, and 150 horsepower and provided stainless steel braided nozzle lines, feed line, fuel line, and stainless steel bottle brackets for systems with a bottle included. These high-quality nitrous oxide systems, designed to fit all electronic fuel injected vehicles with a single throttle body, help you achieve the full performance potential from your engine.

The Proton Plus system includes the legendary 'Lightning 45' bottle valve, which features a .325 in. orifice with a direct-flow pathway and one 45-degree turn to the outlet, helping to provide a consistent inner diameter that supplies outstanding laminar flow, eliminating the potential for power loss.
