w124 - resistor in spark plug wires?
 

Today i checked out my distributor cap and spark plug wires.

The cap had a lot of nasty residue on the copper points. -Dremel'ed it away but will get a new cap asap.

As i understand it, the wires has a specific resistance which may be wrong if i buy aftermarket wires. Right?

My wires are Bougicord wires. Is that aftermarket stuff or OEM?

The resistance in the wires were as follows:

1: 1870 Ohm
2: 2325 Ohm
3: 3219 Ohm
4: 3180 Ohm
5: 4360 Ohm
6: 4940 Ohm

The increasing resistance is of course due to the increasing lenght of the wire.

But if there is this much difference, how can it be a problem to buy aftermarket cables? -OEM's are $240:eek:

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.

If you get new wires, get the Beru wires and forget about all the rest.
