Nitrous Express Direct Port Water Injection 4 Cyl Stage 2 w/Hardlines

If you're pushing a turbocharged or supercharged 4-cylinder engine hard, managing intake air temperatures and preventing detonation is key to making reliable power. This Nitrous Express direct port water injection system is designed to do just that, by injecting a precise mixture of water and methanol directly into each intake runner. This method ensures even distribution to every cylinder, which is crucial for consistent performance and engine health under high boost conditions.

This Stage 2 system features a high-pressure electric pump, robust push-lock hoses, filtered nozzles, and nickel-plated fittings, all built with high-quality components. The real advantage here is the direct port setup, which offers superior distribution compared to single-point injection systems. The included digital progressive controller allows you to fine-tune the water-methanol delivery based on engine load, using simple rotary dials on the controller box. This system is designed to help lower intake air temperatures and increase the fuel's resistance to detonation, allowing you to run more aggressive tuning safely.

This kit comes with hardlines for a clean and professional installation. It's important to note that this system is not CARB approved and cannot be shipped to California. For optimal performance and safety, always follow the manufacturer's installation and tuning guidelines.
