Product Details

If you're looking to add some serious power to your GM LS engine, this Nitrous Express 102mm Nitrous Plate Kit is a solid option. It's designed to fit between your throttle body and intake manifold, making installation relatively straightforward for a nitrous system. This kit is built for a wide range of GM vehicles, including popular models like the Chevrolet Camaro, Corvette, and Silverado trucks, as well as Cadillac CTS and Escalade models.

What sets this kit apart is the billet plate, which is pre-machined to accept a second set of nitrous and fuel passages, allowing for an easy upgrade to a dual-stage system later on. It comes with jetting for a wide range of horsepower gains, from 50 up to 400 HP, so you can tune it to your specific needs. The included ProPower Lightning series solenoids are a notable feature, designed with an improved flow path to keep the nitrous in a dense liquid form for maximum power. They also have an integrated purge port for a cleaner installation and a sleek look, with CNC aluminum bodies topped with carbon fiber cans for reduced weight.

This kit includes everything you need to get it installed, from the solenoids and feed lines to the master arming switch, WOT switch, and all the necessary nuts, bolts, and electrical connectors. Just remember that this system does not include a nitrous bottle, so you'll need to source that separately. It's also important to note that this kit is not CARB approved and cannot be shipped to California.
