Product Overview
Fits LS-powered builds equipped with compatible aftermarket intake manifolds and throttle bodies using the standard 102mm 4-bolt LS pattern. This common pattern is used across numerous aftermarket combinations, including compatible FAST 102, FAST LSXR, Holley 102mm, and other 102mm LS intake applications.
The Nitrous Express 102mm 4-Bolt LS Nitrous Plate System installs between the throttle body and intake manifold, providing a clean way to add anywhere from 50 to 400 wheel horsepower to 102mm-equipped LS combinations.
The 0.95-inch-thick plate is CNC-machined from billet aluminum and delivers nitrous and fuel directly into the intake manifold. The complete system is made in the USA and comes in a wet, single-stage configuration with jetting from 50 to 400 wheel horsepower.
The plate is pre-machined with a second set of nitrous and fuel passages. Adding the NX933D second-stage upgrade creates another stage capable of an additional 50 to 400 wheel horsepower, bringing the plate's total two-stage capability up to 800 wheel horsepower!
A 15300L Lightning Series nitrous solenoid provides the flow capability required for the system's 400-horsepower range, while a 15201L Lightning Series fuel solenoid controls fuel delivery through the plate. Both solenoids are recommended for operation at 18–20 Hz when used with a progressive controller.
The System Includes:
- CNC-machined billet aluminum 102mm 4-bolt nitrous plate
- 15300L Lightning Series nitrous solenoid
- 15201L Lightning Series fuel solenoid
- 6AN nitrous feed line
- Braided stainless steel solenoid-to-plate lines
- Universal solenoid mounting brackets
- Mechanical wide-open-throttle switch
- Relay, wiring, switches, and installation hardware
- Jetting for 50–400 wheel horsepower
- Systems ordered with a bottle include the Lightning 500 bottle valve and stainless steel bottle brackets
Fitment Note: This system fits compatible FAST, Holley, and other aftermarket LS intake and throttle-body combinations using the standard 102mm 4-bolt pattern. Compatibility is determined by the mounting pattern and available clearance, not the intake manufacturer, vehicle year, model, or original factory configuration. Verify the mounting pattern and clearance before ordering.
Fuel Note: The standard system is wet and requires a compatible pressurized fuel source. The required fuel connection or adapter will vary by vehicle and fuel-system configuration.
Dry configurations are also available by calling Nitrous Express at 940-767-7694. A dry configuration requires an aftermarket engine-management system capable of supplying additional nitrous enrichment fuel through the vehicle's injectors.
