How often should I change the spark plugs on my BMW 4 Series?

I recently purchased a used BMW 4 Series and I'm unsure about the recommended maintenance schedule for the spark plugs. How often should I change them to ensure optimal performance? Are there any warning signs to look out for?

Spark plugs should typically be changed every 30,000 miles. However, it's always best to consult your owner's manual for the specific maintenance schedule for your BMW 4 Series.

If your BMW 4 Series is experiencing misfires or a decrease in fuel efficiency, it may be time to replace the spark plugs. Keep an eye out for these warning signs and don't hesitate to change them if necessary.

Being proactive about replacing your spark plugs can save you from potential engine issues down the line. It's a relatively simple and inexpensive maintenance task, so don't overlook it.
