Nitrous Express only uses the highest quality, made in the USA, solenoids on its systems. Don’t be fooled by low price come-ons, the solenoids are the most important component of a nitrous system. The next time you are tempted by a cheap solenoid ask yourself if it has: 
• A limited lifetime warranty
• A guarantee to outflow any comparable solenoid.
• A 100% aluminum body, and a proprietary seat material that resists leakage even when damaged by foreign debris. 
• Lightweight Carbon Fiber solenoid cans to complete the package making it the lightest solenoid ever manufactured.
• The NX exclusive design that allows a flow through purge to give a 100% pure nitrous charge at the solenoid orifice. This insures the hardest hit in the industry! 
• Another NX exclusive is the built in fuel bypass port in the fuel solenoid.
• The quickest off the seat reaction time of any solenoid made today 
• Integral filters to insures long solenoid life, and safety 
• True orifice sizes, NX solenoids have the largest true orifice sizes in the industry 
• A guarantee to open at the highest pressures, some NX nitrous solenoids will open at 2000 PSI 
• Available alcohol compatible seat materials 
• Heavy 14 gauge color coded wires 
• Epoxy encapsulated coils 
When only the best will do it had better be Nitrous Express!
