Ignition Wires -ANY Good Aftermarket Sets?
After plugs (meticulously gapped)/cap/rotor, my 86 560SL still wasn't running right; After perusing the manual, this and other fourms, and having nightmares about 500$ X modules and 1200$ Y modules that MIGHT, POSSIBLY help, I went back to basics. Upon closer examination, I found that the ignition wires on this car "supposedly" maintained at a MB dealreship were original (on an 83K, 18 year old car). One of the reasons that I didn't look and suspect this first was that I couldn't beleive that they could be that old and still actually work at all. Unless they were on their dying last legs, I don't think that I yanked them carelessly when changing the plugs/cap - I used a wrench to break the 18 year seal between rubber, ceramic, metal, and plastic.
So, I got a replacement set. I didn't get the most expensive, or the least expensive (I'm not going to mention the brand-not yet, anyway). I installed them tonight. They were beefy enough, but 5 of them were 1/4" within the same length except for the one I think is #4 (they weren't marked, either!), and the two angled ones were identical. With the fancy "German Engineering" that this company claims, one would think that they would know how to use a FREAKING RULER, and maybe even possibly shell out some money and measure a REAL set when making their own. Maybe somehow someone stuffed the wrong set in the bag or mislabled them, but I find that hard to beleive. One of the clips for the distributor end was just not made correctly, didn't clip worth a darn, and I had to reform (a polite way to say "bend") it with a needlenose so that it would stay in reaonably reliably. No dilectric grease, no instructions, no nothing. The coil wire was so long that I had to tuck some under the coil cap. Instead of the wires being built into rubber coated formed metal tubes (no doubt to keep the heat off of them), the nice people sent me two $0.01 plastic separators. I would have sent the entire $150.00's worth of junk back except that I really want to get this car going (and fortunately, the car now runs just great). Is this "normal"? How much is an OEM set of wires?

Ignitions wires
I just installed a set of Kingborne wires that I purchased through AJUSA Online site They were a perfect fit and very well made. This set even has the two angled connectors which most other sets I've looked did not include.

They don't fit exact because the company is manufacturing a set for all the SL V8s, and on of thge reasons they are cheap is he does them all in one production run. They fit perfect on say, a 380, but on yours they are a little tight. Mercedes gets the ruler out.

Some aftermarket are crap
I won't say who, for now, but I ordered a set for under $100 and the guy I spoke to said they use MB ends but make them up themselves. It sounded okay.
Wrong. I needed the 2 angled plug ends for my Euro SL500 to clear the battery heat shield. I bought them to swap out and found the ends were not terminated correctly. The insulator was cut straight off, not stripped and inserted into the end of the screw connector. THey were not crimped either. I attached the two ends correctly but who knows about the rest. I have a slight miss at idle and can't be sure it's not the spark trying to jump the gap in the plug ends. I will have to change them out again, at my own cost, if I can't find the problem. AJ-USA looks like they do it right. Otherwise I would not buy any aftermarket wires, no matter what the salesman says. If you have to hunt down and problems, it's a sure thing that you don't want to have to wonder about parts you already replaced.
