BMW M3 Maintenance: When should I change my spark plugs?

I just bought a used BMW M3 and I want to make sure I'm keeping up with its maintenance. I'm unsure of when the spark plugs should be changed, as I've heard conflicting advice. Some say every 30,000 miles, while others say every 60,000 miles. What is the recommended interval for replacing spark plugs on a BMW M3?

Hi Ryan, congratulations on your new BMW M3! According to BMW maintenance guidelines, spark plugs should be replaced every 30,000 miles to ensure optimal performance and fuel efficiency. However, if your car is heavily modified or driven aggressively, it may be necessary to change them more frequently at the 60,000 mile mark.

Hello Ryan, great question! BMW recommends changing spark plugs every 30,000 miles, but it ultimately depends on your driving habits and the condition of your car. It's always a good idea to have them checked by a mechanic during routine maintenance to ensure they're functioning properly.
