About this part

Product Details

Nitrous Express is known for making powerful nitrous oxide systems for performance vehicles. This 4-cylinder EFI nitrous kit is designed for gasoline engines that have already seen internal upgrades for higher strength. It uses the patented NX 'Piranha' nozzle, which is a key component for delivering a consistent spray. This system is adjustable, allowing you to tune the horsepower increase from 50 up to 250 HP, with the potential to go even higher if your engine modifications support it, up to 300 HP.

This kit comes with everything you need to get started, including stainless steel bottle brackets, hard lines, the Piranha nozzles, and all the necessary jetting and electrical components. It’s built with high-tech distribution blocks, and you can opt for their 'Next Generation' rail technology if you want an updated fuel rail setup. Keep in mind that for this direct port system to work, you will need to drill and tap your intake manifold to install the nozzles. This is a serious upgrade for engines built to handle more power.

Because this system requires modifications to your intake manifold and is designed for significantly increased performance, it's important to ensure your engine's internal components are up to the task. This kit does not include the nitrous bottle itself, so you'll need to source that separately. Please note that this kit is not CARB approved and cannot be shipped to California.
