About this part

Product Details

Nitrous Express is known for making powerful nitrous oxide systems that are built with quality components. This 90mm Hemi Plate System is designed to give your vehicle a significant power boost, offering anywhere from 50 to 400 horsepower depending on the jetting you choose. It fits a wide range of Chrysler, Dodge, and Jeep vehicles equipped with a Hemi engine, including popular models like the Dodge Challenger, Chrysler 300, and Jeep Grand Cherokee.

The heart of this system is a billet aluminum plate that installs easily between your throttle body and intake manifold, keeping the installation clean and attractive. Nitrous Express includes their Pro Power Lightning series solenoids, which feature an improved flow path to keep the nitrous in a dense liquid form for maximum power. These solenoids also have an integrated purge port, making for a cleaner setup. The solenoids themselves are made from CNC aluminum with carbon fiber caps for a lightweight, high-performance look. This kit comes with jetting for multiple power levels, allowing you to dial in the exact boost you want. It also includes a 12lb bottle with a Lightning 500 valve, braided stainless steel lines, an arming switch, and a TPS activated WOT module for fly-by-wire throttle bodies, plus all the necessary hardware for installation.

This system is configured as a single-stage system out of the box, but can be upgraded to a dual-stage system with an additional part. 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.
