What is the primary benefit of a direct port water injection system?

Direct port systems inject the water-methanol mixture directly into each intake runner. This ensures even distribution to every cylinder, leading to more consistent cooling and better performance gains compared to single-point systems.

What kind of tuning adjustments can I make with the Stage 3 controller?

The Stage 3 controller features an LCD display and allows for fine-tuning of the water-methanol injection percentage across low, mid, and high airflow levels. It also displays real-time engine data like boost pressure and fuel injector duty cycle.

What components are included in this Nitrous Express water injection kit?

This kit includes a high-pressure electric pump, stainless steel hardlines, filtered nozzles, nickel-plated fittings, a composite reservoir, and the Stage 3 digital progressive controller with an LCD display.

Product Details

If you're looking to get the most out of your turbocharged or supercharged four-cylinder engine, this Nitrous Express Direct Port Water Injection system is a serious upgrade. It injects a water-methanol mixture directly into each intake runner, ensuring even distribution to every cylinder. This helps to cool the intake charge, allowing for more aggressive tuning and increased power output, especially under boost.

This Stage 3 system uses a digital progressive controller with an LCD display. You can precisely tune the water-methanol injection percentage for low, mid, and high airflow levels, and the screen shows real-time data like boost pressure and fuel injector duty cycle. The kit includes a high-pressure electric pump, nickel-plated fittings, filtered nozzles, and a composite reservoir. The stainless steel hardlines provide a clean and durable installation route for the fluid.

Because this system injects directly into each runner, it offers superior distribution compared to single-point systems. This is particularly beneficial for high-performance applications where consistent cylinder temperatures are crucial for reliability and power. Remember, this system is not CARB approved and cannot be shipped to California. Always follow the manufacturer's installation instructions carefully.
