Why is my Ford S-Max producing a loud engine noise?

I recently noticed that my Ford S-Max is producing a loud engine noise when accelerating. What could be causing this? I want to make sure my car is in good condition and prevent any potential damage. Any advice?

It's possible that it could be an issue with the exhaust system. You should have a mechanic check it out.

Make sure to regularly check and change your oil. Dirty or low oil can cause engine noise.

I had a similar issue with my Ford S-Max, and it turned out to be a problem with the spark plugs. Try replacing them and see if the noise goes away.
