you could get a set of ignition wires-the complete set for about $120 from the fastlane website-there is a choice of 3 qualities-bosch,beru or other.

that is what i would opt for rather than pay the dealer(stealership) for the oem.

i am satisfied that the standard of bosch or beru would be the equivalent to the oem product and, if fact, these 2 suppliers do provide parts to mercedes benz and the dealer puts the badge on them to charge the extra money.
