Nitrous Express 8 Cyl VXL Direct Port 4 Solenoids Nitrous Kit (200-500HP) w/No Bottle

If you're looking to add serious horsepower to your V8 engine, a direct port nitrous system like this one from Nitrous Express is a popular way to go. This kit is designed for 8-cylinder engines and includes everything you need to get started, except for the nitrous bottle itself. It's engineered to provide a significant power boost, ranging from 200 to 500 horsepower, depending on the jetting you choose.

What sets this system apart are the NX Lightning Series solenoids. They feature an improved flow path that directs nitrous and fuel above the seat and out the bottom, which Nitrous Express claims is unmatched by other solenoids. The nitrous solenoids have a built-in purge port, allowing you to connect a purge valve directly to the solenoid body. This setup helps eliminate air pockets that can cause inconsistent nitrous delivery. The fuel solenoids include a bypass port for a small return line to the tank, which helps prevent trapped air and lean spikes. These solenoids are constructed with CNC-machined aluminum bodies and topped with lightweight carbon fiber cans. Nitrous Express uses high-quality, USA-made components for these critical parts.

This comprehensive kit includes eight extended-length VXL nozzles, two nitrous solenoids, two fuel solenoids, anodized aluminum distribution blocks, 3/16-inch stainless steel hard lines, and nickel-plated fittings. You also get the necessary jetting for 200-500 horsepower, 6AN nitrous feed lines, a high-flow 6AN Y-fitting, a wide-open throttle switch, 40-amp relays with harnesses, and a master arming switch. It also comes with stainless steel bottle brackets. Remember, this kit does not include the nitrous bottle itself, so you'll need to source that separately.
