BMW M3 Ignition Systems

To start and run dependably, your BMW M3 needs an equally reliable ignition. The best one to install is original, made by BMW specifically for your sedan. Your factory BMW M3 ignition system works simply. Turn your key. An ignition switch activates, sending current through a starter solenoid and working with an ignition coil to draw voltage from your battery. The resulting charge reaches your spark plugs, atop the combustion chambers in your engine cylinder head. Each captures electricity, igniting your engine's fuel-air mixture; your starter motor cranks your engine, and that gets your car running, keeping it running on its own power. The entire process occurs in sync, with your engine pistons pumping and all the other necessary auto parts moving, thanks to a timing mechanism or electronic controls. If your car stalls or won't start at all, however, if you can't turn the key, your dash lights flicker, or your starter motor doesn't turn, these are signs of a possible bad ignition. Luckily, our auto parts department has the OEM ignition system parts you need to repair or replace those in your BMW M3. Buy them from us online today and take care of the job in short order.
