Nitrous Express 4150 Hitman Plus 4-BBL Nitrous Kit (50-200HP) w/15lb Bottle

This Nitrous Express 4150 Hitman Plus kit gives you the actual components to add a significant power boost to your vehicle. Inside the box, you'll find the Phase 3 nitrous plate, a 15lb nitrous bottle equipped with the Lightning 45 bottle valve, stainless steel bottle brackets, a 40-amp relay, and a Wide Open Throttle (WOT) switch with its mounting bracket. This system is designed to be an introductory package for those new to using nitrous oxide, offering a straightforward way to gain extra horsepower.

The heart of this system is the Phase 3 nitrous plate, which is built for reliable performance and superior fuel and nitrous distribution. Unlike older designs with spray bars that can sag or block airflow, this plate technology aims for better atomization and consistent delivery across all cylinders. You get four adjustable horsepower settings right out of the box: 50, 100, 150, and 200 horsepower. This adjustability lets you dial in the power increase to suit your needs and driving conditions. For those who want even more power down the road, this kit is upgradeable to 300 HP with the addition of a larger nitrous solenoid and different jetting.

This kit is a well-built option for getting started with nitrous oxide. It includes the necessary components for a basic installation, such as the WOT switch that activates the nitrous system only when your engine is under full throttle, and a relay to handle the electrical load. Remember that this system is not CARB approved and cannot be shipped to California. Always follow manufacturer instructions for installation and safe operation.
