Gen III Stinger 4500 Dominator Nitrous Plate System (50–600 HP)

Maximize plenum distribution and eliminate runner puddle with the Nitrous Outlet Gen III Stinger 4500 Nitrous Plate System.

Engineered specifically for 4500 Dominator carburetor flange intake manifolds, this race-proven wet nitrous kit features an industry-first Extended Reach Stinger Cone. By dropping the discharge point deeper into the intake plenum, the Gen III design minimizes fuel and nitrous wall-wetting, ensuring precise cylinder-to-cylinder distribution across high-rise intake manifolds and spacer applications.

Whether you are dialing in a bracket racer or building a heads-up street/strip monster, this system delivers instant, reliable power adjustable from 50 to 600 HP—with an included .178 nitrous solenoid capable of flowing up to 700 HP.

Key Features

• Extended Reach Gen III Stinger: Directs nitrous and fuel deeper into the plenum to prevent runner-wall impact and improve air/fuel distribution.

• 360° Precision Atomization: 16 CNC-machined discharge ports (8 nitrous, 8 fuel) create a complete 360-degree spray pattern for total charge saturation.

• High-Flow Capacity: Out-of-the-box jetting for 50–600 HP with a heavy-duty .178 nitrous solenoid rated up to 700 HP.

• Billet Aluminum Construction: CNC-machined 6061 billet aluminum with a sleek black anodized plate and signature red anodized Stinger cone.

• Clean, Professional Fitment: Includes prefabricated, pre-bent stainless hardlines and a Deep Break Center solenoid bracket for a custom, low-profile engine bay setup.

• Single Entry Design: Fits all standard 4500 Dominator carb flanges (carbureted or carb-style EFI intakes).

Product Overview

Advanced 360° Fuel Atomization & Distribution

At the core of the Gen III Stinger is Nitrous Outlet’s proprietary center-discharge cone. Featuring 8 dedicated nitrous ports and 8 fuel ports, it projects 16 finely atomized plumes outward in a uniform 360-degree pattern. This thorough mixing reduces tuning variability, stabilizes air/fuel ratios across all cylinders, and optimizes combustion efficiency for maximum horsepower gains.

Built for High-Horsepower Race Applications

Constructed from high-grade 6061 billet aluminum, every component is engineered to withstand extreme racing conditions. Clear CNC-engraved port markings make plumbing straightforward, while the anodized finish protects against harsh fuels and environmental wear.

⚠️ Critical Installation Notice (Directional Plate)

The Gen III Stinger is a directional nitrous plate. Proper orientation is mandatory to prevent uneven mixture distribution and potential engine damage:

1. Fuel Solenoid must face the FRONT of the vehicle.

2. Nitrous Solenoid must face the REAR of the vehicle.

3. The engraved "FUEL" label on the plate must point toward the FRONT of the engine.
