About this part

Product Details

If you're looking to add serious horsepower to your 4150 carburetor setup, this Nitrous Express kit is designed to do just that. It's built for applications that use alcohol fuel and can support anywhere from 100 to 500 extra horsepower, giving you a significant performance boost when you need it most. This system uses a spraybarless plate design, which is an updated approach to nitrous injection. This means there are no spray bars that can sag, split, or block airflow, leading to more consistent fuel and nitrous distribution and better atomization for improved performance.

The Phase 3 series plate technology is a key part of this kit, offering improved distribution and atomization compared to older designs. It's a well-built system that includes everything you need to get started, such as limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, and a composite nitrous bottle. You also get stainless steel bottle brackets and an extra-long supply line, making installation more straightforward. This kit is available for alcohol-fueled vehicles, and it's a solid option for racers and performance enthusiasts looking for a substantial power increase.

This kit comes complete with the necessary components to integrate nitrous oxide into your engine's fuel system. Remember that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
