The NOS Motorcycle/ATV 4-Stroke Fogger Wet Nitrous System brings that proven race-winning performance directly to your powersports vehicle in a complete, easy-to-install package.

Fogger™ Technology:

At the heart of this system is the legendary NOS Fogger™ nozzle design, which delivers a precisely atomized mixture of nitrous and fuel directly into the intake. This wet-system approach ensures consistent power delivery and superior fuel distribution compared to dry nitrous systems, protecting your engine while maximizing horsepower gains.

Key Features:

• Wet system design — simultaneously injects nitrous and supplemental fuel for safe, reliable power increases
• Super PowerShot nitrous solenoid and PowerShot fuel solenoid for precise, responsive delivery
• Fogger 2™ nozzles with flare-style jets for optimized atomization and consistent performance
• Handlebar-mounted push-button activation for intuitive, on-demand power
• Complete bolt-on kit — includes nitrous bottle, solenoids, Fogger nozzles, fuel pump, jetting, filters, fittings, tubing, brackets, switch, hose, and all necessary electrical and mounting hardware
• Designed specifically for 4-stroke powersports engines, from single-cylinder applications to multi-cylinder configurations
• Detailed, easy-to-follow installation instructions included

With the included jetting, these systems are engineered to deliver a 30–40% increase in horsepower and torque. For modified engines or custom power targets, the system is fully tunable with additional jet selections. A 12-volt DC power supply with a minimum of 12 amps is required for operation.
