is there any sparkplug wires that can be used instead of oem?
 

is there any other car that has similar sparkplug wires that are cheaper for the m103? paying 100 bucks everytime i change my wires is a bit steep. just wondering if anyone knows of any that will work. thanx guys:D

If you are concerned over $100 every 100k miles the 103 might not be the best choice....

If you are strapped for cash right now, measure resistance on each wire using a multimeter and check it to what the wire says. If resistance is fine, they are probably okay. Just

well the thing is the set that i bought recently i broke pulling them out and was looking for a alternative because im cheap lol

m103 and cheap should not be used in the same sentence;). As for price, bosch sets can be found for well under $100. Also, mercedes has a special pair of pliers designed especially for pulling plug wires so you don't break them. Inexpensive and worth it.

thanx guys you got that right m103s arnt cheap price u gotta pay tho

I was able to buy a Bosch ignition wire roll for use in my 109 The correct Bosch spark plug adapters are also available as required . Not cheap. Low price alternate is the VW shops with quite similar Bosch parts like coils CB points, cap rotors And brakes parts for fintails.

got a link for those special pliers?

The pliers are listed in the Performance Products web page but they are around $41. Seems a little expensive to me.

Identical spark plug pliers available at any big box auto parts store (Pep Boys, AutoZone, et al). They are NOT an MB special tool. About $5. or less.

ya my michanic actually gave me a set of them pliers after i broke mine was just trying to avoid paying 100 bucks again lol

Have you looked at the fastlane store under the "Buy parts" link above? You can buy a meter of spark plug wire and an end, just replace the wire that you broke off for only a few bucks. IMO the M103 isn't that expensive an engine to work on, nor is it that complicated (aside from CIS-E system)

I cant remember the website but a vendor online had some high quality spark plug wires for Mercedes, non oem brand but they were of high quality. Cannot recall them.

But nothing wrong with buying from here

Before installing any set of wires, it would be a good idea to check the resistance on each, particularly looking for consistency. Just a few years ago, Bosch and Beru OEM wires were wildly inconsistent for their M102 sets, while NGK was much more consistent.

If you are concerned, why not buy copper-strand high voltage ignition wire from a race shop? Buy a roll and make your own

Then you'll need resistor plugs. I wouldn't change the combination MB made.
