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 accelerator pedal is fully depressed (wide-open throttle). It automatically disengages the nitrous when you ease off the pedal, providing a safer and more controlled power boost.

What is spraybarless technology?

Spraybarless technology means the nitrous and fuel are introduced into the intake manifold without traditional spraybars. This design helps to atomize the mixture more effectively and distribute it more evenly across all cylinders, leading to better performance and consistency.

What else might I need to install this kit?

While this kit includes the main plate system, solenoids, fuel adapter, TPS switch, and a 5lb bottle, you may need additional items such as nitrous bottle brackets, nitrous lines, and potentially a fuel pressure gauge. Always consult the manufacturer's installation guide for a complete list of recommended components and tools.

About this part

Product Details

If you're looking to add a significant boost of power to your Dodge Hellcat or Demon, this Nitrous Express plate system is designed to do just that. It bolts between your throttle body and intake manifold, making it a straightforward way to introduce nitrous oxide into your engine. This system is built for these specific high-performance Mopar vehicles, ensuring a clean installation and reliable operation when you need that extra surge of power.

What sets this kit apart is its spraybarless technology, which helps atomize and distribute the nitrous oxide more evenly throughout the intake. The billet plate itself is well-built and integrates the solenoids directly, giving you a super clean look under the hood. Installation is simplified with a direct-plug-in fuel line adapter, so you won't have to cut your factory fuel lines. Plus, the included TPS Autolearn switch means the nitrous will only engage when your accelerator is at wide-open throttle and will automatically shut off when you lift, adding a layer of safety and control.

This kit comes complete with a 5lb nitrous bottle, so you have a good starting point for your nitrous supply. Remember that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and operation.
