Our Gen III High Output Kit is ideal for any GM LSX-powered (LS1, LS2, or LS6) vehicle looking for a serious power upgrade from the standard ZEX? system. This kit features giant, high-flow nitrous and fuel solenoids and -4AN nozzle feed lines. All of this high-flow hardware allows you to spray from 100-250 hp. Also included with this ZEX? system is Fuel Shear? Technology, which injects enrichment fuel directly in the nitrous plume for better atomization.
