If you're looking to add a significant horsepower boost to your electronic fuel injected vehicle with a single throttle body, this Nitrous Express Proton Plus system is a solid choice.

The kit comes complete with a 5lb nitrous bottle featuring a high-flow Lightning 45 valve, stainless steel bottle brackets, a single Shark nozzle, nozzle adapter, and all the necessary stainless braided lines for both the nozzle and the feed line, plus a stainless fuel line. It also includes a master arming switch, a wide-open throttle switch, a 40-amp relay, and a relay harness, ensuring you have every nut, bolt, and connector needed for a complete installation.

This is a comprehensive package designed to get you up and running with a significant power upgrade. Remember that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and safe operation.
