Greetings forum members,

The Beru plug wires on my 1972 350sl, m117 engine vary in resistance from 6.05K ohms to 6.36K ohms.
I couldn't find information in the forum archives on permissable resistance variance.
So, unless anyone replys with this information, I'll probably replace all the resistor plug ends or the complete wire set.
Parts Shop offers the ends for $25.00 each. x 8 = $200.00 for wire ends only!
FastLane offers a complete Bosch wire set for $76.59.
I don't know if the wire set is solid core copper, but if it is, it seems to be a much better unless Beru is that much higher in quality.
If so I would like to know the price of a new Beru wire set before I make a decission.

Thanks in advance for all replys,

Knarf

If your plug wires are resistor wires they are supposed to vary with length. If they are solid with resistor ends they shuld be pretty much the same. Either way 6k ohms doesn't sound bad. Resistor wires generally need to be replaced if they are over 25k ohms.

The resisance will vary slightly with length. Are you having problems? I usually clean the connections well and adjust/tighten them. Also lay the wires out in a neat pattern away from hot surfaces when installing them. A "spagettii' configuration can cause them to interact
