About this part

Product Details

The Nitrous Express Single Entry Billet Crossbar system starts with a .178 inch nitrous jet, setting the stage for a controlled and potent power increase. This setup is designed for racing classes that permit only a single nitrous and fuel jet, offering a streamlined approach to adding significant horsepower. Unlike older designs with spray bars that could sag or disrupt airflow, this crossbar plate represents an updated approach, ensuring a consistent spray pattern without those potential issues.

At the heart of this system is the billet aluminum Lightning 500 bottle valve. It’s not just about looks; this valve is packed with features like two integrated gauge ports, a 5/8 siphon tube, and a large .500 orifice. The improved flow path minimizes restrictions, and the valve itself weighs nearly a pound less than older brass models, contributing to overall system efficiency. This kit is built for 4500 flange manifolds and comes with everything you need to get started, including specific solenoids, a custom bracket, high-flow braided stainless lines, nickel-plated fittings, a wide-open throttle switch, a 6AN feedline, a master arming switch, and an amp relay with harness. The included jetting is calibrated to support power gains from 250 to 650 horsepower.

This system is designed for those looking to add substantial, tunable power to their vehicle. It’s important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
