Spark Plugs

Air and fuel are mixed to create the perfect balance for your spark plug to ignite and start the engine. An ignition coil sends a spark through the plug to your engine's cylinder. They produce an electric spark inside your car's cylinder head. Other than being useful components for triggering combustion, spark plugs assist in the dissipation of the extreme heat generated inside the combustion chamber. Spark plugs require at least 20,000 volts for them to function appropriately, even though the engine voltage drops over time. You can recognize whether your BMW's spark plugs are faulty by looking out for various signs such as poor fuel economy, loud noises coming from the engine, difficulty in starting up the engine, and reduced engine performance. Some other notable signs of bad spark plugs include a drop in gas mileage, failure to accelerate, hard starts, and engine misfires. To be on the safe side, make sure your BMW's spark plugs are regularly checked and serviced.
