Nitrous Express 4500 Covert Crossbar Plate Stage 6 Nitrous Systems

The Nitrous Express 4500 Covert Crossbar Plate Stage 6 Nitrous Systems are a high-performance, stealthy nitrous setup for 4500-flange carburetors, designed to support 50-300+ HP gains. These systems utilize a CNC-machined, black-anodized plate with internal spray bars for superior atomization, and include braided stainless lines, Lightning Series solenoids, quality fittings, and stealthy design that installs under the carb.

Key features and benefits:

* The CNC-machined crossbar plate eliminates traditional round spray bars, preventing sagging, rotation, and airflow disruption
* Stealth Technology—designed to be hidden beneath the carburetor, providing a stock look while offering significant power
* High Flow Solenoids—the system utilizes Stage 6 Pro Power Lightning solenoids for rapid response and improved flow
* Superior Distribution—provides exceptional fuel atomization and air/fuel distribution directly into the intake manifold
* Comprehensive kits typically come with Lightning Series solenoids, custom solenoid brackets, braided stainless lines, billet aluminum fittings, and, in full complete kits, a 15 lb. bottle with the Lightning 45 valve
* Versatility—the system works with 4500-series (Dominator) flanges and includes jets for various horsepower levels, usually covering 50-300+ HP depending on the specific kit
