OEM BMW Spark Plugs

The engine in your BMW must burn a ratio of fuel to oxygen to produce power. Its factory spark plugs are what start the combustion process. How do they work, though? Put your key into its lock cylinder. Now, turn it to activate your ignition switch. Many other ignition parts begin working -- everything from your battery and starter motor to a solenoid and an ignition coil. Together, they create a small electrical charge and send it to the plugs. When electricity reaches their leads, the air and gas inside your engine begin burning, and that releases power. With some pumps of your engine pistons and turns of your crankshaft, your vehicle's many other parts get going. Without spark plugs, though, that BMW you love driving wouldn't start at all. To make matters worse, spark plugs eventually go bad. Their leads can rust or widen, and as a result, their charges can weaken. Plus, they can cause engine misfires and shutdowns. Broken spark plugs, however, usually cause severe engine cylinder damage. Luckily, those made by BMW get built to last, for as many as 100,000 miles. That's millions of ignitions. Just be sure you change any that are close to the mileage limit recommended by your owner's manual.
