About this part

Product Details

Nitrous Express is known for making powerful nitrous oxide systems that help racers and performance enthusiasts get more out of their engines. This 4150 4-BBL/Gasoline Nitrous Kit is a prime example, designed to add anywhere from 100 to 500 horsepower to your vehicle. It uses an advanced spraybarless design, which is a notable step up from older systems. This means you get better fuel and nitrous distribution to all cylinders, leading to more consistent power delivery and outstanding atomization for efficient combustion.

What's really smart about this design is that it eliminates spray bars altogether. You won't have to worry about them sagging, splitting, or blocking airflow into your intake manifold, which can happen with traditional setups. This innovation in nitrous plate technology ensures reliability and performance, especially for those looking for a significant power boost. The kit comes with everything you need to get started, including limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, a 15-pound nitrous bottle, stainless steel bottle brackets, and extra-long supply lines for flexible installation.

This kit is a solid option for budget-minded racers who want a substantial increase in power. It's important to note 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, especially when dealing with high-performance nitrous systems.
