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

A dry nitrous system, like this one, injects only nitrous oxide into the intake manifold. It relies on your engine's computer (ECU) to add the correct amount of fuel to match the extra air. A wet system injects both nitrous and fuel together.

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

For this dry direct port system, you'll need an engine management system that can be programmed to add fuel enrichment when the nitrous is activated. This typically means an aftermarket ECU or a factory ECU with tuning capabilities.

What is the horsepower range this kit can support?

This kit includes jets that allow for power increases from 50 to 300 horsepower per stage. The included tech card provides specific flow data to help you tune for your desired power level.

About this part

Product Details

If you're looking to significantly increase the power output of your 4-cylinder engine, a direct port nitrous system is a serious consideration. This Nitrous Express Dry Direct Port Nitrous Kit injects nitrous oxide directly into each cylinder through specialized nozzles, offering a more precise and potent power boost compared to single-point injection systems. Because it's a 'dry' system, it relies on your engine's management system to add the necessary fuel enrichment, making it crucial to have an ECU capable of handling this extra fuel demand.

This kit comes with jets that allow for power increases ranging from 50 to 300 horsepower per stage, giving you a lot of flexibility to tune your setup. You'll also find a tech card included, which provides detailed flow data in pounds per hour for each jet setting, helping you dial in your air-fuel ratio accurately. The system features a high-flow .093 NX Lightning Solenoid, a wide-open throttle (WOT) switch to ensure nitrous is only active when you're accelerating hard, and a 15lb nitrous bottle with stainless steel bottle brackets.

Installation includes a 4AN nitrous feed line, a relay and harness for proper electrical control, and all the necessary hardware to get the system mounted and plumbed. You can choose between 1/16 NPT (default) or 1/8 NPT nozzles for the direct port entry into your intake manifold. Please note that this system is not CARB approved and cannot be shipped to California.
