Nitrous Express 4 Cyl SX2 Nozzle Nitrous Kit (100-300HP x 2) w/o Bottle

If you're looking to significantly boost the power of your 4-cylinder engine, this Nitrous Express direct port system is designed to give you precise control over fuel and nitrous delivery to each cylinder. This setup uses a patented SX2 dual-stage nozzle, meaning each nozzle can actually provide two separate stages of nitrous, allowing for a very refined power increase. It's a well-built system aimed at getting the most consistent performance possible from your engine.

The kit comes with everything you need to get the nitrous flowing, including four aluminum and carbon fiber Lightning solenoids, stainless steel bottle brackets, and stainless steel hard lines. You also get the SX2 nozzles themselves, all the necessary jetting to tune your power output, and all the electrical components required for installation. The dual-stage nature of the SX2 nozzles is a notable feature, offering flexibility in how you apply the power boost, from a moderate increase to a substantial jump of up to 300 horsepower per stage. This system is also available for alcohol-based fuels, adding to its versatility.

Keep in mind that this kit does not include the nitrous bottle, so you'll need to source that separately. Installation involves drilling and tapping your intake manifold to properly seat the nozzles, so it's a job that requires careful work. Because this system is not CARB approved, it cannot be shipped to California.
