The Nitrous Express NX dual-nozzle nitrous kit for GM EFI engines provides adjustable power from 100–300 wheel horsepower in 25HP increments without the complexity of direct port. Dual Shark nozzles and high-flow Lightning solenoids give broad tuning range, and the kit includes a stainless bottle bracket, extra-long braided N2O line and all hardware needed for installation (less bottle).
