Call BMA and other places like MSD. I know of other kits out there for the M20, M30 & S38. These other kits are also superior with better shielding. The only thing is it is a little more difficult to bend and snake into place. The pros, better shielding, cheaper price & quality.

well ... I remember once that the cable is molded with the plugs they are not like those old ones that u screw in the plug. still ... it's not a big deal, u need to get good shielded wires that stands 15KV without leaks, the ones with the thin wire are the best as far as I know. I also remember once I was told that the wires used by BMW are resistive wires, it should read between 3.5K - 6K depending on the length between the distributor and the plug.

I suggest you get the distributor and plugs and build one, just keep the old one untouched, if it works without any misfiring and u feel the difference then u do the same for the other side ... otherwise u plug in the old wires and find better material for the rebuild.

good luck

Bought a seta while back from Bav Auto ~$400 for both sides. I kept the old ones, if you want them to rebuild you can have 'em.

may I know if you gained any power difference after this change? is it more than 10%?

Just a moment, we are talking here from M20 to M70 engine. The V12 spark plugs are much more expensive.

Here is a possibility to make it cheaper for a V12

Here they might be cheaper

that's cool, what made you decide that you need new wires? shimmy engine? or what

basicly they just look shitty, looks like a couple have been replaced at one time or another. The car runs with a check engine thing and while I tear into it I want to replace everything that I can (plugs, wires, valve seals, check banjo bolts etc). I want this thing to be a 25k car not the POS 8.5K car that it is. I have all the front end parts ready to install as soon as I have time and motovation. The new trunk spoiler and tint completely transformed the car, the body/paint is immaculate.

sorry for my late reply, I wish I can do what ur gona do. I have serious stearing fluid leak and lots of small stuff here and there and I can no longer find the time to do it. as you said you need time and motivation. good luck dude ..

The arcing in damp conditions convinced me to make the change. Obviously the old ones were tired at 16 or 17 years old.
I'm sending the old ones off to Jeff. I'm sure he'll report on the rebuilding project.
The only thing special about them is all the little plastic sleeves they are threaded through, which I would think are re-usable or even unnecessary.
I paid ~$400 for both sides at the time. I regret doing it now, Jeff has the better idea I think.
