Product Details
The Nitrous Express Single Entry Billet Crossbar nitrous plate system uses a .178 inch nitrous jet and a .178 inch fuel jet, designed specifically for 4500 flange intake manifolds. This setup offers the desirable crossbar spray pattern, but in a configuration that’s legal for racing classes that permit only a single nitrous and a single fuel jet. Unlike older designs, this system features no spray bars that can sag or disrupt airflow, making it a truly updated approach to crossbar nitrous plate technology.
This kit comes complete with a 10lb nitrous bottle equipped with the billet aluminum Lightning 500 bottle valve. This valve isn't just about looks; it's packed with practical features like two integrated gauge ports, a 5/8 inch siphon tube, and a large .500 inch orifice. Its improved flow path minimizes turns, and the valve itself is nearly a pound lighter than older brass models. The system also includes high-flow braided stainless steel lines, nickel-plated fittings, a custom solenoid bracket, a wide-open throttle switch, a 6AN feedline, a master arming switch, an amp relay with harness, and jetting calibrated for 250 to 650 horsepower gains.
This Nitrous Express kit is a well-built option for those looking to add significant power. It’s important to note 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.
