Nitrous Express 4150 Covert Crossbar Plate System Stage 6 50-300HP (15lb Bottle)

If you're looking to add a significant power boost to your vehicle with a 4150 flange carburetor, this Nitrous Express Covert Crossbar Plate System is a serious option. This Stage 6 system is designed to inject anywhere from 50 to 300 horsepower, giving you the flexibility to tune your power output for different driving scenarios. It's a well-built system that aims for improved fuel and nitrous distribution directly under your carburetor.

What sets this system apart is its CNC machined design that does away with traditional spray bars. Instead, it uses a unique crossbar plate that sits between your carburetor and intake manifold. This design helps ensure better atomization and more even distribution of the nitrous and fuel mixture into each cylinder. The system also features an improved flow path with only one 45-degree turn, minimizing restrictions. It comes complete with a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines from the solenoid to the plate, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay with its harness, and jetting for all 50-300HP levels. The included 15lb bottle is topped with the Lightning 45 bottle valve, which not only looks great with its billet aluminum construction but also flows exceptionally well and is lighter than older brass valves.

This kit is designed for a direct fit on 4150 flange manifolds. Remember 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.
