How often should I replace my BMW M1's spark plugs?

I recently purchased a used BMW M1, and I'm not sure how often I should replace the spark plugs. It currently has 50,000 miles on it and I want to make sure I'm maintaining it properly.

Spark plugs should ideally be replaced every 30,000 miles, but it also depends on driving habits and conditions.

If your BMW M1 is running rough or has trouble starting, it's a good idea to check and potentially replace the spark plugs.
