Nitrous & Fuel Solenoids
MPS has two types of nitrous solenoids in stock. The standard MPS nitrous solenoid, P/N 1-0389 features a .063” orifice good for up to 100 horsepower and our "400+" HP solenoid, P/N 1-0401 that has a giant .125" orifice. The plungers for both solenoids use Teflon seal material for long life with no seal deterioration or swelling. The MPS Fuel Solenoids, P/N 1-0390 feature a .125” orifice and fuel resistant FKM plunger seal material. Watch for these solenoids showing up on more and more top bikes!

NX Lightning Series Solenoids flow great, weigh less and look sexy. The key to maximizing nitrous horsepower is to keep the nitrous in liquid form until it is injected into the engine. Sharp bends cause nitrous flow to become turbulent which causes gaseous bubbles to form in the nitrous flow.
Expansion areas also cause the nitrous to go gaseous. Liquid nitrous makes more power than gaseous nitrous – Period! 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. The result is more horsepower! Lightning series solenoids are CNC machined from lightweight billet aluminum and topped with carbon fiber cans for the ultimate in weight savings. 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. The NX Lightning series fuel solenoids feature 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.
