Normal operation of the ignition system of your BMW 3-Series greatly depends on numerous electronic and mechanical devices. Every journey starts with putting the key in the ignition cylinder (or pressing the start button): if there is something wrong with this component, your car may not start at all. Sometimes the air-fuel mixture detonates when the piston is in a wrong position: such pieces of equipment as ignition knock sensors detect detonation and send signals to make the current ignition angle a bit later. Ignition relays, condensers, and many other parts are vital to the whole ignition system: they ensure its perfect operation.
When choosing ignition components for your vehicle, always bear in mind that these parts are affected by heat and vibrations. It is reasonable to purchase quality, reliable products that were made by well-established companies with an excellent reputation. Our online store cooperates with famous aftermarket manufacturers such as Standard, Beck Arnley, Bosch, Genuine, and Fast, so we carry BMW 3-Series ignition relays, sensors & switches that feature superior quality and an extended lifespan. And we do our best to make our prices competitive.
