What is a 'dry' nitrous system and how does it work?

A dry nitrous system injects only nitrous oxide into the engine's intake. It relies on the engine's fuel system, controlled by a compatible engine management system, to add the extra fuel needed for combustion. This means your ECU must be programmed to add fuel when the nitrous is activated.

What is 'direct port' injection and why is it beneficial?

Direct port injection means a separate nitrous nozzle is installed into the intake runner for each cylinder. This provides a more precise and even distribution of nitrous compared to a single nozzle system, leading to more consistent power gains and better control over the air-fuel mixture for each cylinder.

What else might I need to install this kit?

Beyond the included hardware, you'll need a compatible engine management system capable of adding fuel enrichment. It's also highly recommended to have your ECU professionally tuned for this system to ensure optimal performance and engine safety. You'll also need a place to mount the 12lb bottle.

About this part

Product Details

This is the Nitrous Express Dry Direct Port Nitrous Kit, designed for 6-cylinder engines. It's a serious power adder that injects nitrous oxide directly into each cylinder through specialized high-flow dry nozzles. Because it's a dry system, it relies on your engine management system to add the necessary fuel enrichment through the engine's existing fuel system. This setup is ideal for tuners looking to significantly increase horsepower and torque for performance applications.

What sets this kit apart is the direct port injection. Instead of a single nozzle spraying into the intake manifold, this system has a dedicated nozzle for each cylinder. This allows for more precise and even distribution of the nitrous charge, leading to more consistent power delivery and better control. The kit comes with jets that can add anywhere from 75 to 375 horsepower per stage, giving you a wide range of tuning options. You also get a tech card that details the lbs./hr flow rate for each jet setting, which is crucial for proper tuning. It includes a .093 NX Lightning Solenoid, a Wide Open Throttle (WOT) switch to ensure nitrous is only activated when you're giving it full throttle, stainless steel bottle brackets, a 4AN nitrous feed line, a relay and harness, and all the necessary hardware for installation. You can choose between 1/16 or 1/8 NPT nozzles depending on your specific setup needs.

This kit includes a 12lb nitrous bottle, which is a common size for many performance builds. Remember that this system requires an engine management system capable of adding fuel enrichment. It's also important to note that this kit is not CARB approved and cannot be shipped to California. Always consult with a professional tuner to ensure proper installation and tuning for your specific engine and application to maximize performance and reliability.
