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

A dry system injects only nitrous oxide into the intake manifold or cylinders. It relies on the engine's existing fuel system, managed by the ECU, to add the necessary fuel to compensate. A wet system injects both nitrous oxide and fuel simultaneously.

What horsepower gains can I expect with this system?

This system includes jets that allow for power increases ranging from 50 to 300 horsepower per stage. The exact gains will depend on your engine's capabilities, tuning, and the specific jetting you choose.

Does this system include a nitrous bottle?

No, this system does not include a nitrous bottle. You will need to purchase a compatible nitrous bottle separately.

About this part

Product Details

Nitrous Express is well-known for their performance nitrous oxide systems. This Dry Direct Port Nitrous System is designed for 4-cylinder engines and injects nitrous oxide directly into each cylinder using high-flow NX Dry Nozzles. This setup requires an engine management system capable of adding nitrous enrichment through the vehicle's fuel system, making it a powerful addition for those looking to significantly increase horsepower.

This system comes with jets that allow for power increases ranging from 50 to 300 horsepower per stage, giving you flexibility to tune your performance. You'll also receive a tech card detailing the lbs./hr flow data for each jet setting, which is crucial for proper tuning. The kit includes a .093 NX Lightning Solenoid, a Wide Open Throttle (WOT) switch, stainless steel bottle brackets, a 4AN nitrous feedline, a relay and harness, and all the necessary hardware for installation. The nozzles are available with either 1/16 or 1/8 NPT threads, so you can choose the best fit for your setup.

Please note that this system is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning. Ensure your engine management system is compatible with dry nitrous systems before installation.
