About this part

Product Details

If you're looking to add a significant power boost to your vehicle with a 4150 flange carburetor, this Nitrous Express Covert Crossbar Plate System is a robust option. This system is designed to inject a precise mixture of nitrous oxide and fuel directly into your intake manifold, increasing horsepower for improved acceleration and performance. It's a popular choice for enthusiasts who want a noticeable increase in power without major engine modifications.

What sets this system apart is its "covert" crossbar design. Instead of traditional spray bars that can sometimes sag or disrupt airflow, this system uses a CNC-machined plate with an improved flow path that only has one 45-degree turn. This design helps ensure excellent atomization and even distribution of the nitrous and fuel mixture across all cylinders, leading to more consistent power delivery. The kit comes with everything you need to get started, including jetting for a wide range of horsepower gains from 50 to 300 HP, a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay with harness, and a 5lb nitrous bottle equipped with the sleek Lightning 45 bottle valve. The Lightning 45 valve itself is designed for great looks and improved flow compared to older brass valves.

This Stage 6 system is a comprehensive package for those serious about performance. 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.
