NOS Diesel Nitrous Oxide Injection System

The NOS Diesel Nitrous Oxide Injection System is purpose-engineered for turbo diesel engines, delivering proven horsepower and torque gains through precisely metered nitrous oxide injection. These dry-style systems are designed around the unique combustion, boost, and fueling demands of diesel powerplants, making them compatible with both stock and modified applications — from daily drivers and tow rigs to full-competition builds.

NOS pioneered nitrous oxide injection technology in the late 1970s and has remained the industry standard ever since. Nearly every significant nitrous performance milestone has been achieved using the NOS brand, and that same engineering heritage is fully applied to this diesel-specific product line.

Key Features:

• Diesel-specific dry-style injection — nitrous oxide is introduced through the intake system, with additional fuel supplied via the existing fuel injectors, keeping installation clean and straightforward
• Broad, adjustable power gains — an easy 50 HP can be added with no upgrades required to the fuel system or electronics; further gains are achievable with supporting fuel system and tuning modifications
• Cleaner combustion — nitrous oxide promotes more complete fuel burn, helping reduce exhaust smoke and lower exhaust gas temperatures (EGTs)
• High-flow Super ProShot solenoid — heavy-duty solenoid construction ensures consistent, reliable nitrous delivery under all operating conditions
• Adjustable jetting — multiple included jet sizes allow power levels to be tuned to match your specific build and goals
• Compatible with performance upgrades — vehicles with ECU tunes, injector upgrades, and aftermarket fueling benefit even further from nitrous-aided combustion
• Complete kits — every system ships with a nitrous bottle, bottle brackets, nitrous feed line, solenoid, electrical wiring, and comprehensive installation instructions
• Made in the USA — manufactured to the exacting quality standards NOS has upheld for decades in motorsports and performance applications

Whether the goal is stronger towing capability, quicker quarter-mile times, or simply unlocking the full potential of a diesel engine, the NOS Diesel Nitrous Oxide Injection System delivers a repeatable, proven solution. Nitrous oxide injection remains one of the best power-per-dollar performance upgrades available, and NOS is the brand that perfected it.
