My 2000 C230 Kompressor has 120,000 miles and i am looking to change the spark plugs. My friend gave me some Bosch spark plugs that are three pronged and are already gapped to 0.40. Is this correct because i was reading in the manual it takes 1.00mm gap? if not can anyone give me advice on what to buy or what direction i should go?

secondly, do you know the size of the star socket to remove the spark plugs?

third, i am missing a 5mm hex screw on the spark plug cover. seems the cover takes 3 screws and i am missing one.

any responses would be greatly appreciated.

just take an old plug out and make sure they're the same as what you got. if they are supposed to be 3 electrode plugs you can't gap those types of spark plugs, so don't worry about that. star socket to remove spark plugs??? spark plugs are either gonna be a 5/8 or 13/16 (not sure if you're talking about a torx socket for coils maybe? in that case just buy a set of torx sockets, male and female, they're worth having around) and if you're missing one screw, i wouldn't even worry about it.

btw, doesn't your car have coil on plug with suppressor boots? i'd replace the suppressors too if i was doing the job.

First, you're in a world of mixed messages or really mixed units.

1mm = 0.040", or 1mm equals 40 thousandth of an inch. Now 1 inch = 25.4 mm.

See there really was a reason to study math in school.

Take one of the three remaining cover screws to Home Depot and match it. Or it's not going anyplace, so just forget it.
