Commonly Asked Questions About Spark Plugs
- What do they do? Ignite the fuel and air in your vehicle's engine, causing it to combust and produce the power the engine needs to run.
- How do they work? As part of a process called spark ignition. It starts when your key turns in the lock cylinder. Several ignition parts activate: the ignition switch triggers, and the car battery, plus a starter motor, a starter solenoid, and an ignition coil, begin generating electricity. The plugs' leads capture it.
- What happens then? The above-mentioned combustion occurs, and the engine's pistons, its crankshaft, the alternator, and many other parts and systems start running.
- What are the symptoms of a bad one? Look for corrosion, excessively wide leads, plug wear or breakage, and worsening conductivity. Some less obvious signs include hard starts, a reduction in gas mileage, a misfiring engine, rough idling, and trouble accelerating.
- When should they be changed? On the one hand, if you see the signs mentioned above. On the other hand, when you do an engine inspection, and the results require it. Either way, before they exceed your owner's manual's suggested mileage limits. Before you order new ones, however, be sure they're genuine.
- Why buy genuine OEM? BMW designs and builds them specifically to fit your car or SUV model, a fit-and-finish guarantee that you may not always get from aftermarket spark plugs.
- Where can I order them? From our auto parts store.
