Nitrous Express Direct Port Water Injection 8 Cyl Stage 3 w/Hardlines

Nitrous Express is well-known for their performance nitrous oxide systems, and they bring that same focus on power and control to their water-methanol injection kits. This Stage 3 Direct Port Water Injection system is designed for 8-cylinder engines, injecting the water-methanol mixture directly into each intake runner. This direct port setup ensures excellent distribution to every cylinder, which is key for consistent performance and engine protection under boost.

What sets this Stage 3 system apart is its advanced digital progressive controller. Unlike simpler systems, this controller features an LCD screen that lets you finely tune the water-methanol injection based on low, mid, and high airflow levels. You can monitor critical data like boost pressure, fuel injector duty cycle, and the exact percentage of water-methanol being injected. This level of control allows you to optimize your engine's response and safety, especially when pushing your vehicle hard. The kit includes a high-pressure electric pump, push-lock hoses, filtered nozzles, nickel-plated fittings, and a composite reservoir, all built with high-quality components.

Because this system injects directly into each runner and offers such precise control, it's a solid option for serious performance builds. Keep in mind that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and tuning.
