MSD coils > stock coils for about 2 years apparently.

Are the MSD'* giving you trouble? It'* hard to believe all three coils would be failing & have readings so close to each other. Maybe MSD used a heavier gauge wire in those coils.

Compared to other MSD coils on this forum, I'm at half the typical resistance on the secondaries as others. That equates to a very low spark voltage if you know your transformer theory.

You didn't say if they're giving you trouble. Isn't the voltage determined by the number of windings. If they used a heavier gauge wire & the same # of windings wouldn't the voltage be the same & the resistance lower?

Well, my MSD coils are more than 2 years old. I bought them on Katie'* Birthday. Sept 10, 2003.

I'm going to fire off an email to MSD about them.

Hmm, mine aren't bad, I don't think, but they don't jive with those numbers, either.

Email sent. I'll post the reply when it comes (probably in a couple days). I measured mine when new, just need to find the topic.

Edit: Found this:

3 is a long way from 7.8 in two years. :?

That is the problem with MSD'*... That is why I always have said MSD coils looky good; OEM coils work. It is not worth the $$ and the minor performance you will get out of them if you have to replace the coils ever two years. If MSD would replace them after two year then it might be a diferent story but good luck trying to get them to do that. Willwren by chance do you know how many miles you have on them? I want to compare it to a few of my friends MSD coils that took a dump.

Got about 20k on them. That'* pretty close.
