The Edelbrock Pico-Style Fuel Injector offers controlled fuel flow for better power, throttle response and economy. It is supplied with pressurized fuel by the fuel pump and is capable of opening and closing many times per second. The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open. The injectors are mounted in the intake manifold to facilitate fuel spray directly at the intake valves. These fuel injectors are compact with quick response times.
