Why is the BMW M3 engine not performing as it used to?

I've noticed that my BMW M3's engine is not running as smoothly as it used to. It seems to lack power and is making unusual noises. What could be causing this and what can I do to fix it?

It's possible that your BMW M3's engine is experiencing a decrease in performance due to a clogged air filter or dirty fuel injectors. I would recommend taking your car to a trusted mechanic to have it checked and have these components cleaned or replaced if necessary.

Another possibility is that your BMW M3's engine is low on oil. Check the oil level and top it off if needed. If the issue persists, it may indicate a bigger problem that should be addressed by a professional.
