Nitrous Express 4150 Covert Crossbar Plate Stage 6 Nitrous Systems

The Nitrous Express 4150 Covert Crossbar Plate Stage 6 Nitrous Systems are a high-performance, hidden nitrous solution for carbureted engines, designed to fit beneath the carb for a stock appearance. These systems utilize a CNC-machined billet aluminum plate with internal spray bars to provide superior fuel/nitrous atomization and distribution for 50-300+ HP gains and often include Lightning solenoids and a 15 lb. bottle.

Key features and benefits:

* Hidden Design—the Covert Crossbar plate installs inside the intake manifold rather than on top of it, keeping the system concealed and eliminating the need for a taller cowl hood
* Superior Atomization—CNC-machined internal passages replace traditional round spray bars, eliminating issues with sag, rotation, or airflow disruption
* High Flow Capacity—designed to support from 50 to over 300 horsepower (with some, like this one, rated up to 1000 HP), making it suitable for both mild and extreme street/strip applications
* Complete System—kits generally include Pro Power Lightning series solenoids, stainless steel braided lines, jets, a master arming switch, a WOT switch, and a 15 lb. nitrous bottle with a Lightning 45 valve
* Installation—while this kit requires specific intake manifold clearance, the system is designed to provide maximum power efficiency with precise 4150-flange fitment
