Founded in 1996 and headquartered in Wichita Falls, Texas, Nitrous Express (NX) has earned a reputation as a premier developer of nitrous oxide and water/methanol injection systems. Built “by racers, for racers,” NX began with a clean-sheet design and introduced innovations like the first 4150-series Stage 5 nitrous plate in 1996. Their proprietary Lightning solenoids and Assassin plates minimize turbulence and ensure optimal nitrous/fuel distribution—rigorously dyno-tested for consistency and efficiency

In 2018, NX expanded its offerings by acquiring water/methanol specialist Snow Performance, creating a combined powerhouse in engine-boosting technologies. Today, their product range includes bolt-on and universal nitrous kits for cars, trucks, and powersports, featuring carbon-fiber bottles, progressive controllers, and custom plate/fuel systems—with tech support from real, live experts.

NX continues to push the envelope in both performance and reliability. With USA-based engineering, CNC machining, and a customer-first ethos, Nitrous Express delivers precision power increase solutions for hardcore street riders and competitive motorsports alike.
