About this part

Product Details

If you've already upgraded the internals of your 4-cylinder gasoline engine with stronger components, this Nitrous Express EFI Nitrous Kit is designed to help you unlock more power. This system is built for modified engines and allows for significant horsepower gains, adjustable from 50 up to 300 horsepower using the included jetting. It's a direct port system, meaning it injects the nitrous and fuel directly into each cylinder's intake runner for more efficient and consistent power delivery.

The kit includes the essential components to get you started, such as a composite nitrous bottle, stainless steel bottle brackets and hard lines, the patented NX 'Piranha' nozzles, and all the necessary electrical parts. The distribution blocks are high-tech, and you have the option to upgrade to their 'Next Generation' rail technology. Because this is a direct port system, it does require you to drill and tap your intake manifold to install the nozzles, so be prepared for that modification during installation.

This Nitrous Express system is a serious upgrade for those looking to significantly increase their engine's output. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always ensure your engine's internal components are rated for the horsepower you intend to run.
