1995 C280 30K mikes.
Well I've had most of the 30K mile sevice
done and I am thinking of changing the plugs myself. This car is mostly used for city driving. Is there a recommended plug (partsshop?) and gap, if it needs to be gapped at all. I could replace them with what it has but, if there is something more 'advanced'
out there, I'd like to know.
