Nitrous Express GM LS 90mm Nitrous Plate Kit (50-400HP) w/15lb Bottle

Starting with the billet plate, this Nitrous Express system is designed to fit between your throttle body and FAST 102 intake manifold on GM LS engines. This direct-fit design makes installation straightforward and keeps the plumbing looking clean. It’s a single-stage system out of the box, but the plate is pre-machined with extra passages, so you can easily upgrade to a dual-stage setup later by adding another component.

This kit comes with jetting for a wide range of horsepower gains, from 50 up to 400 HP, so you can tune it to your needs. The ProPower Lightning series solenoids are a key part of this system. They feature an improved internal flow path that keeps the nitrous in a dense liquid state, which means you get more power using less nitrous. Plus, they have an integrated purge port, making it simple to connect a purge valve directly to the solenoid for a cleaner look and less plumbing. The solenoids themselves are made from CNC aluminum with carbon fiber cans, keeping weight down.

You’ll get everything you need to get this system installed, including the 15lb nitrous bottle, stainless steel bottle brackets, a master arming switch, a wide-open throttle (WOT) switch, all necessary nuts, bolts, and electrical connectors, plus the feed lines. This system is compatible with a wide range of GM vehicles, including popular models like the Chevrolet Camaro, Corvette, and Silverado. Please note this system is not CARB approved and cannot be shipped to California.
