BMW Fuel Injectors have been a part of the BMW magic for a long time now. From the late 1970s on, BMW has relied on fuel injection to make horsepower and keep emissions low, and they’ve done it with great success. Whether your car is equipped with four, six, eight, or twelve of them, the BMW fuel injector operates in pretty much the same manner. A solenoid opens a tiny needle valve at precisely the right moment, and a high-pressure squirt of atomized fuel enters the intake port.

Since the openings in your BMW fuel injectors are so tiny, clean fuel is essential for the system to work properly. High pressures are necessary too, since the fuel has to be injected in a fine mist in order to burn rapidly. And the timing of the spray provided by your BMW fuel injectors has to be minutely controlled in order to keep power up and emissions down. That’s why electronic controls are so vital to your car—they let your BMW fuel injectors to their job well.
