How do I replace the spark plugs in my 2003 C240 Mercedes Benz at my home and what special tools do I need to complete the process? Please advise. Claude Wiseman

The book time to remove and replace spark plugs on this vehicle is 3 hours for a trained tech as these engines are highly complicated and unless you have work on these engines you probably should have a shop handle this
