Bypass port allows you to connect a purge valve directly to the body of the nitrous solenoid, ensuring there is no trapped air in the body of the solenoid
Has great flow characteristics, weighs less and looks great
Raised inlet and a bottom exit eliminates up to four 90 degree turns and one expansion area in the body of the solenoid
Provides more horsepower
The Nitrous Express Lightning gasoline stage 1 solenoid with .150 orifice flows great, weighs less and looks great. NX lightning solenoids feature a raised inlet and a bottom exit which eliminates up to four 90 degree turns and one expansion area in the body of the solenoid. Lightning series solenoids are CNC machined from lightweight billet aluminum and topped with carbon fiber cans for the ultimate in weight savings. Lightning series fuel solenoids features a bypass port which allows you to connect a small bypass/return line to your tank. This eliminates lean spikes caused by trapped air between your fuel pressure regulator and the fuel solenoid. Nitrous Express uses the highest quality materials and is made in USA solenoids. The solenoids are the most important component of a nitrous system. Lightning series solenoids come standard in many NX nitrous systems and are also available separately as an upgrade to your existing nitrous system. The NX Lightning series nitrous solenoids feature a bypass port which allows you to connect a purge valve directly to the body of the nitrous solenoid. Connecting the purge valve to the body of the nitrous solenoid not only looks cleaner, it ensures that there is no trapped air in the body of the solenoid.
