How often should I change the spark plugs on my BMW M1?

The spark plugs on a BMW M1 should be changed every 30,000 miles to ensure optimal performance and fuel efficiency. They can become corroded or dirty over time, leading to misfires and decreased engine power. It is important to stay on top of regular maintenance to keep your BMW running smoothly.

You should always refer to your owner's manual for specific maintenance intervals for your vehicle. However, as a general rule, changing your spark plugs every 30,000 miles is a good practice for optimal engine performance.

If you notice any issues with your vehicle's performance, such as misfires or decreased power, it may be a sign that your spark plugs need to be replaced sooner than the recommended interval. Keep an eye out for any warning signs and address them promptly.
