Product Overview
Fits 2014–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models and 2015–2026 Chevrolet Tahoe, Suburban, GMC Yukon, and Yukon XL models equipped with the factory 5.3L V8, four-bolt throttle body, and matching factory intake manifold.
The Nitrous Express GM 5.3L Truck and SUV Nitrous Plate System installs between the factory throttle body and intake manifold, providing a clean way to add anywhere from 50 to 250 wheel horsepower without cutting the factory fuel line.
The 0.54-inch-thick plate is CNC-machined from billet aluminum and uses NX Spraybarless technology to deliver nitrous and fuel directly into the intake manifold. The nitrous and fuel solenoids are integrated into the plate for a compact installation with less external plumbing and a cleaner appearance.
This system comes in a wet, single-stage configuration with jetting from 50 to 250 wheel horsepower. The included direct-plug-in fuel-line adapter connects the fuel side of the system to the factory low-pressure fuel line without any cutting or permanent modifications.
The included TPS Autolearn wide-open-throttle switch activates the system at wide-open throttle and shuts it off when the accelerator is released. The integrated solenoids are recommended for operation at 18–20 Hz when used with a progressive nitrous controller.
The plate and system are made in the USA.

- CNC-machined billet aluminum 5.3L four-bolt nitrous plate

Fitment Note: This system fits the factory four-bolt throttle-body and intake-manifold interface used on the listed 5.3L GM truck and SUV applications. It is not intended for 2014 or earlier Tahoe, Suburban, Yukon, or Yukon XL models. Applications with an aftermarket intake manifold or throttle body must retain the factory mounting pattern and provide sufficient clearance for the 0.54-inch-thick plate.
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 the additional nitrous enrichment fuel through the vehicle's injectors.
