About this part

Product Details

If you're looking to add serious horsepower to your GM LS engine, this Nitrous Express adapter plate kit is designed to make that happen. It bolts right between your throttle body and intake manifold, giving you a clean way to inject nitrous oxide and fuel directly into your engine. This system is built for performance, using spraybarless technology to ensure the nitrous and fuel mix perfectly for better atomization and distribution, which means you get more consistent power when you hit the go pedal.

The installation is made much simpler thanks to the integrated solenoids on the plate itself, keeping things tidy under the hood. You also get a direct-plug-in fuel line adapter, so there's no need to cut into your factory fuel lines. A key feature is the TPS Autolearn switch; this smart piece of tech ensures the nitrous only activates when your throttle is fully open and shuts off automatically when you lift off the gas, giving you control and safety. The kit comes with jetting options to tune for anywhere from 100 to 400 horsepower, so you can dial in the power increase you want. It includes everything you need to get started: a stainless braided N2O line, master arming switch, relay, harness, and all the necessary hardware. Plus, it comes with a 10lb bottle featuring a billet aluminum Lightning 500 valve and stainless bottle brackets.

This kit is a comprehensive solution for adding significant power to your LS engine. Remember that this system is not CARB approved and cannot be shipped to California. Always follow the manufacturer's instructions for safe installation and operation of nitrous oxide systems.
