If you're looking to add a significant power boost to your carbureted performance engine, this Nitrous Express kit is designed for that purpose. It's specifically built for 4150-style carburetors and is compatible with alcohol fuel systems, offering a range of horsepower increases from 50 to 300 HP. This system uses an advanced spraybarless plate design, which helps ensure consistent fuel and nitrous distribution for improved performance and reliability. Unlike older designs with spray bars, this plate won't sag, split, or block airflow, making it a more dependable option for demanding applications.

This kit comes with everything you need to get started, including the nitrous plate, limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, a 5lb nitrous bottle, stainless steel bottle brackets, and an extra-long supply line. The spraybarless technology is a notable advancement, providing better atomization and distribution of the fuel and nitrous mixture. This means you get more efficient combustion and a stronger power increase when you activate the system. It's a well-built setup designed for racers and performance enthusiasts who want a straightforward way to add serious horsepower.

Because this is an alcohol-specific system, it's crucial to ensure your fuel system is set up correctly to handle alcohol. Please note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
