About this part

Product Details

The Nitrous Express Proton Plus Nitrous Kit is a well-built system designed to add significant horsepower to your electronic fuel injected vehicle, provided it has a single throttle body. This kit is a popular choice for those looking to boost their engine's power output, offering a range of adjustable horsepower settings to suit different driving needs. It combines performance with durability, all housed in a compact module that's easy to mount.

At the heart of this system are high-quality solenoids made in the USA, capable of supporting up to 150 horsepower gains. The black anodized aluminum housing isn't just for looks; it actively helps dissipate heat, which is crucial for the longevity and extreme durability of the solenoids, especially under demanding use. This Proton Plus kit comes with jetting options for 35, 50, 75, 100, 125, and 150 horsepower, giving you the flexibility to tune your power delivery. You'll also find a single Shark nozzle, a nozzle adapter, stainless braided lines for the nozzle and a long feed line, a stainless fuel line, a master arming switch, a wide-open throttle switch, a 40-amp relay, and all the necessary nuts, bolts, and electrical connectors to get the job done.

While this kit doesn't include the nitrous bottle itself, it provides everything else needed for a complete installation on compatible vehicles. 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.
