The Nitrous Express 15300L Pro-Power Lightning Nitrous Solenoid flows great, weighs less, and looks awesome. 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.
