These NOS Powershot systems are an excellent way to increase the horsepower of your engine. They use a thin, 1/2 in. injector plate that fits between your intake and carburetor. Highly accurate spray bars within the plate simultaneously inject both nitrous and fuel into the manifold, creating a smooth rush of extra power on demand. They're easy to install and are factory preset to provide 125 HP for V8 applications, or 90 HP for V6s. The kits come complete with an unfilled 10 lb. nitrous bottle, nitrous and fuel solenoids, fuel filters, 12 ft. of -4 AN braided fuel line, all necessary hardware, and instructions.
