About this part

Product Details

If you're looking to add a significant power boost to your carbureted gasoline engine, this Nitrous Express kit is designed for that purpose. It's built for 4150 style 4-barrel carburetors and can deliver an adjustable increase of 50 to 300 horsepower, making it suitable for a wide range of performance applications.

The Phase 3 series plates are engineered for superior fuel and nitrous distribution, ensuring excellent atomization for a cleaner burn and more efficient power gain. This kit comes with everything you need to get started, including Lightning solenoids with a limited lifetime warranty, a heavy-duty 40-amp relay, a 10lb nitrous bottle, stainless steel bottle brackets, and an extra-long supply line.

This kit is available for alcohol applications as well, offering flexibility for different fuel types. Please note that this system is not CARB approved and cannot be shipped to California. It's important to consult local regulations and ensure proper installation for safe and effective operation.
