About this part

Product Details

This Nitrous Express kit gives you everything you need to add a nitrous oxide injection system to your GM LS engine. You get the 112mm billet adapter plate, which bolts between your throttle body and intake manifold for a clean installation. It also includes a 12lb nitrous bottle with a billet aluminum Lightning 500 valve and stainless steel bottle brackets. The system is designed for GM LS engines with 112mm throttle bodies and can be jetted for horsepower gains from 100 to 300 HP, with included jets for 35, 50, 75, 100, 125, 150, 200, 250, and 300 horsepower levels.

The adapter plate itself uses Spraybarless technology, which helps atomize and distribute the nitrous and fuel mixture more evenly into your engine. The solenoids are integrated directly into the plate, keeping the installation tidy. You also get a direct-plug-in fuel line adapter, so you won't have to cut your factory fuel lines. A TPS Autolearn switch is included to ensure the nitrous only activates when your throttle is wide open and shuts off automatically when you lift off the pedal, adding a layer of safety and control.

This kit comes complete with a stainless braided N2O line, a master arming switch, a relay, a relay harness, and all the necessary hardware. It's a comprehensive package designed to get you up and running with a significant power boost. Please note that this system is not CARB approved and cannot be shipped to California.
