About this part

Product Details

If you're looking to add significant power to your GM LS engine, this Nitrous Express adapter plate kit is a solid option. It bolts right between your throttle body and intake manifold, making installation straightforward. The system uses Spraybarless technology, which helps atomize the nitrous and fuel mixture really well for consistent distribution across all cylinders. This means you get a smoother power delivery when you hit the go-button.

What's neat about this kit is how clean it mounts. The solenoids are built right into the plate, so you don't have extra lines cluttering up your engine bay. It also comes with a fuel line adapter that plugs directly into your factory lines, so you won't need to cut anything. For safety and ease of use, it includes a TPS Autolearn switch. This smart little device ensures the nitrous only activates when your throttle is fully open and shuts off automatically when you lift your foot, preventing accidental activation or bogging.

This kit is jetted for a wide range of power gains, from 35 to 300 horsepower, and the bottle is a 15lb unit with a billet aluminum Lightning 500 valve. You'll also get all the necessary hardware, a stainless braided N2O line, a master arming switch, and a relay harness to get everything wired up. Just remember, this system is not CARB approved and cannot be shipped to California.
