Will it hurt my BMW 840i Gran Coupe to drive with old spark plugs?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
