American nitrous oxide specialist

Nitrous Express, often shortened to NX, is an American brand specialising in nitrous oxide for motorsport and performance. The range covers everything from simple street systems to advanced multi-stage drag racing setups. Because nitrous requires precise control of both gas and fuel, the brand focuses on solenoids, jets and distribution that meter correctly, and on accessories such as pressure gauges and bottle heaters that keep pressure stable from run to run.

Nitrous Express’ key products

Complete kits are the obvious starting point. Wet systems add both nitrous and fuel through a nozzle or plate, while dry systems add only nitrous and let the engine management or injectors handle the fuel. Plate systems mount between the intake and throttle body, and fogger nozzles give precise distribution on larger setups. On top of that come bottles in several sizes, bottle heaters, solenoids, pressure gauges, switches, purge kits and jets in many sizes for fine tuning. See each product for engine fitment.

Frequently asked questions

What is the difference between a wet and a dry nitrous system?

A wet system adds both nitrous and extra fuel at the same time, typically through a nozzle or plate. A dry system adds only nitrous, and the extra fuel is supplied by the injectors. The choice depends on the engine and the power you want.

Why use a bottle heater?

The pressure in a nitrous bottle drops as it gets cold. A bottle heater keeps the bottle at a stable pressure, so the system delivers the same amount of nitrous every time and the setup becomes more predictable.
