Product Details

If you're looking to significantly increase the power output of your vehicle, this Nitrous Express 4150 4-BBL/Alcohol Nitrous Kit is designed for serious performance gains. This system is built for carbureted applications that run alcohol fuel, offering a substantial horsepower boost ranging from 50 to 300 HP. It utilizes an advanced spraybarless design, which is a notable improvement over older technologies. This design ensures better fuel and nitrous distribution, leading to more consistent power delivery and improved atomization.

The Phase 3 series plate technology is at the heart of this kit, providing superior distribution without the common issues associated with traditional spray bars. Since there are no spray bars to sag, split, or obstruct airflow, you get a more reliable and efficient system. This kit comes complete with everything you need to get started, including limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay for stable power, and a 15-pound nitrous bottle. It also includes stainless steel bottle brackets for secure mounting and extra-long supply lines for flexible installation.

This system is a solid option for racers and performance enthusiasts who want a significant power upgrade. Remember that this kit is specifically for alcohol-fueled applications and is not CARB approved, meaning it cannot be shipped to California. Always consult the manufacturer's installation guide for proper setup and safety procedures.
