Should I replace the spark plug wires when replacing the plugs/dist. cap and rotor? I always have on my cars in the past, but I think I remember seeing a post here that mentioned that the wires on a Mercedes should be good for the life of the car. It seems to me that the resistance of these wires would change over time, like on any other car. True? Thanks in advance.

This subject has been discussed many many times here. There is a search function in the upper right corner of this page you can use to search Tech Help. Give it a try.

The short answer is that the wires rarely ever fail but, the tips do. Replace the tips.
