About this part

Product Details

The Nitrous Express Dominator Hitman Plus Nitrous Kit starts with a Phase 3 series nitrous plate, a notable advancement in nitrous performance. This plate design avoids traditional spray bars that can sag, split, or obstruct airflow, instead offering superior distribution and atomization for more consistent power delivery.

This kit is designed as an introductory system for those new to nitrous oxide, offering a low-cost entry point without sacrificing essential features. It comes standard with four adjustable horsepower settings: 50, 100, 150, and 200 HP, allowing you to tailor the power increase to your needs. The kit includes a Lightning 45 bottle valve, stainless steel bottle brackets for secure mounting, a 40-amp relay, and a wide-open throttle (WOT) switch with bracket to ensure the system activates only when you're at full throttle.

What sets the 'Plus' version apart is its upgradeability. You can enhance this system to Stage Six capability and even up to 300 HP by adding a larger nitrous solenoid and appropriate jets. This means the kit can grow with your experience and performance goals. The 15lb nitrous bottle is included, providing a substantial supply for multiple uses.
