About this part

Product Details

If you're looking to add a significant power boost to your vehicle, a nitrous oxide system can be a game-changer. The Nitrous Express 4150 Hitman system is designed for those new to nitrous, offering a straightforward way to increase horsepower without breaking the bank. This kit is specifically built for 4-barrel carburetors, making it a direct fit for many performance applications.

What sets this kit apart is its innovative Phase 3 nitrous plate. Unlike older designs that use spray bars, this plate offers superior fuel and nitrous distribution and atomization. This means you get a more consistent and effective delivery of the nitrous charge, leading to improved performance. Plus, without spray bars, you don't have to worry about them sagging, splitting, or obstructing airflow, which can happen with other systems. The Hitman kit comes with three distinct horsepower settings – 100, 150, and 200 HP – allowing you to tailor the power increase to your needs and your engine's capabilities. This makes it an excellent introductory system for anyone curious about nitrous power.

This kit does not include a nitrous bottle or the necessary lines to connect to it, so you'll need to source those separately. It's also important to note that this system is not CARB approved and cannot be shipped to California. Always ensure your engine is in good condition and properly tuned before installing a nitrous system, and refer to the manufacturer's instructions for proper installation and operation.
