About this part

Product Details

If you're looking to add significant power to your Hemi-equipped vehicle, this Nitrous Express 90mm Hemi Plate System is a comprehensive solution. It's designed to fit between your throttle body and intake manifold, making for a clean and straightforward installation on a wide range of Chrysler, Dodge, and Jeep models, including popular choices like the Dodge Charger, Jeep Grand Cherokee, and Dodge Challenger. This system is built to deliver a substantial power boost, with included jetting that allows you to tune for anywhere from 50 to 400 horsepower.

The kit comes with everything you need to get started. You get a billet aluminum plate, a 10lb nitrous bottle equipped with a Lightning 500 valve, and Pro Power Lightning series solenoids. These solenoids are a notable upgrade, featuring CNC aluminum bodies with carbon fiber caps for reduced weight and an improved internal flow path that helps keep the nitrous in a dense liquid state for maximum power. The system also includes braided stainless steel lines, a master arming switch, and a TPS activated Wide Open Throttle (WOT) module specifically for fly-by-wire throttle bodies. Every nut, bolt, and electrical connector required for installation is included, ensuring you have all the necessary components.

This system is configured as a single-stage system out of the box, but can be easily upgraded to a dual-stage system with an additional part. The included jetting covers a broad range of power increases, allowing you to tailor the performance to your needs. For a more advanced setup, you can add a purge valve directly to the integrated purge port on the nitrous solenoid for a cleaner look and simpler plumbing.
