The "official" Mercedes procedure is to change wires individually as required.
The wires are about $35 each at a dealer, so 12 X 35 = $420.
This is not a POS 'merikun car where every service is a "why don't we do this?" scam.
OE wires are pryed off the plugs using a 17mm wrench, i.e. they don't just pull off.
