What is the difference between a dry and a wet nitrous system?

A dry nitrous system injects only nitrous oxide into the engine. It relies on your engine's computer or fuel system to add the extra fuel needed to match the nitrous. A wet system injects both nitrous and fuel together through a single nozzle or distribution block.

What kind of engine management system do I need for this kit?

This dry direct port system requires an engine management system capable of adding nitrous enrichment through the engine's fuel system. This typically means a programmable ECU or a system that can adjust fuel delivery based on nitrous activation.

What is included in the 'all necessary hardware' for installation?

The kit includes the main components like the solenoid, nozzles, WOT switch, bottle brackets, feedline, and wiring harness. It also includes the jets for tuning and a tech card. You will need to supply your own nitrous bottle and potentially some custom fittings or lines depending on your specific intake manifold and engine bay layout.

About this part

Product Details

Nitrous Express is well-known for performance nitrous oxide systems, and this Dry Direct Port Nitrous Kit is a prime example of their focus on precise fuel delivery. This system is designed for 4-cylinder engines and injects nitrous directly into each cylinder using high-flow NX 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, making it a more integrated approach to power adders.

You get a lot of flexibility with this kit. It includes jets that allow for power increases from 50 to 300 horsepower per cylinder, and a tech card details the pounds per hour flow rate for each jet setting. This helps you fine-tune the system for your specific engine's needs. The kit comes with a .093 NX Lightning Solenoid, a wide-open throttle (WOT) switch to ensure nitrous is only active 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. The nozzles are available in either 1/16 NPT (which is the default) or 1/8 NPT, giving you an option for how they connect to your intake manifold.

This kit is intended for off-road use and is not CARB approved, so it cannot be shipped to California. It's important to have a robust engine management system in place to properly control the fuel delivery when using this nitrous kit.
