How does the TPS Autolearn switch work?

The TPS Autolearn switch monitors your throttle position. It's programmed to only allow the nitrous system to activate when your throttle is fully open (wide-open throttle). When you lift your foot off the accelerator, the switch automatically disengages the nitrous flow.

What is spraybarless technology?

Spraybarless technology means the nitrous is injected directly through small ports in the plate, rather than through a separate spraybar. This design helps to atomize the fuel and nitrous mixture more effectively and distribute it evenly into the intake manifold.

What else might I need to install this system?

While this kit includes the main nitrous plate, solenoids, fuel line adapter, TPS switch, and a 10lb bottle, you may need additional items such as a nitrous bottle bracket, appropriate nitrous lines, and potentially a fuel pressure safety switch depending on your specific setup and tuning preferences. Always refer to the manufacturer's installation guide for a complete list.

About this part

Product Details

If you're looking to add serious horsepower to your 2015-2020 Dodge Challenger or Demon, this Nitrous Express nitrous plate system is a well-built option. It's designed to bolt directly between your throttle body and intake manifold, making installation more straightforward than some other systems. The spraybarless technology helps ensure that the nitrous is evenly distributed for consistent performance, and the integrated solenoids keep the engine bay looking clean.

This kit comes complete with a 10lb nitrous bottle and a direct-plug-in fuel line adapter, so you won't have to cut into your factory fuel lines. A key feature is the TPS Autolearn switch, which means the nitrous will only activate when you're at wide-open throttle and automatically shut off when you lift your foot, adding a layer of safety and control. This system is designed to eliminate sharp turns in the nitrous flow path, which helps maintain optimal pressure and atomization.

While this system is designed for a clean and relatively easy installation, it's important to note that it is not CARB approved and cannot be shipped to California. For optimal performance and safety, always follow the manufacturer's installation and tuning guidelines.
