About this part

Product Details

Nitrous Express is known for making reliable nitrous oxide systems for performance applications. This 4150 4-BBL/Alcohol Nitrous Kit, part number 50045-00, is designed for racers looking to add significant horsepower to their vehicles, offering a range from 100 to 500 horsepower depending on the jetting you choose. It's built around their Phase 3 series plates, which represent an updated approach to nitrous plate technology.

What sets this kit apart is its spraybarless design. Unlike older systems that use spray bars which can sag, block airflow, or break, this plate distributes the nitrous and fuel mixture more evenly. This means you get better atomization and more consistent power delivery. The kit comes with limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, stainless steel bottle brackets, and an extra-long supply line, so you have the core components needed to get started. It's also available for alcohol carbureted applications.

This kit does not include a nitrous bottle, giving you the flexibility to choose the size and type that best suits your setup. Remember, this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and tuning to achieve the desired horsepower gains safely.
