About this part

Product Details

The Nitrous Express direct port EFI system uses a patented 'Piranha' nozzle, a key component that allows for precise fuel and nitrous delivery. This system is designed for 4-cylinder gasoline EFI engines that have already been upgraded with stronger internal engine components, as it can add anywhere from 50 to 300 horsepower. The adjustability means you can fine-tune the power increase to match your engine's capabilities and your driving needs.

This kit comes with everything you need to get started: a 15lb nitrous bottle, stainless steel bottle brackets and hard lines for a clean and durable installation, the Piranha nozzles, jetting to select your desired horsepower level, and all the necessary electrical parts. The high-tech distribution blocks are standard, with an option for 'Next Generation' rail technology if you want an updated look and function. Keep in mind that this system requires drilling and tapping into your intake manifold for proper installation of the nozzles.

Because this is a significant power adder, it's intended for engines that have already been reinforced to handle the extra stress. Always follow the manufacturer's instructions carefully during installation, especially when modifying your intake manifold. This system is not CARB approved and cannot be shipped to California.
