It takes 16 plugs and they were changed at 60,000 miles by Mercedes, a few days before I bought the car. Well, 16 of them were. The front plug on every cylinder was a little loose and greased. The back plugs were bone dry and far too tight. Full main d all history strikes again
So, because Of this changing plugs has actually made a difference. It starts with a lot more zing and throttle response is far smoother where before at low throttle openings it felt a little flat.
They also did a gearbox oil change at 60,000 but now I’m not so sure so will get that done next month when I get back.
Dave!
