how to keep coils alive for 30k+

Guppies? Anyone?

Also they are really just a simple transistor. These are solid state components that are easily prone to overheating with just current, let alone high heat from our little rotary. If transistors aren't designed to carry large amounts of current they aren't going to handle heat well, like Maniac said.

If you want to separate the coil section and show us how you can saturate and fry it, we will all applaud politely, commend you on your "ingenuity" (much in the same way we congratulate competitors in the Special Olympics) and then go on with our lives in the real world.
The Old Style "Single" Coil in the Y-Tube Vid Demo looks like the type which is Oil Filled,

it is
Anyway from Bosch Australia..
Since the first Kettering ignition system was introduced by Bosch in 1925 to replace magneto style ignition systems, the ignition coil has remained virtually unchanged. The familiar oil filled coil proved itself more than capable of providing a suitable high tension spark to keep pace with over 50 years of automotive development.
However the rapid progress of automotive engine technology since the late 70's brought about the need for improvements in ignition system performance. So Bosch introduced the transformer coil. Bosch Australia has been supplying this style of coil as original equipment to the Australian vehicle manufacture's since 1987.
Today we offer a range of coils from traditional oil filled to transformer and electronic to suit a wide range of aftermarket applications.

I got mine from O'Reilly. I worked there a couple years ago and have dealt with Borg Warner quite a bit while I worked there. They (Borg Warner) seem like a pretty good stock replacement. Even if they only like 10K miles it takes 25 minutes to swap them out. I bought mine for about $135 in Edmond, Ok. If I do have any problems I'll just swap them out at the O'Reilly's in Stillwater. They overnight ship to all their stores everyday, unlike Autozone (also worked there).
I was talking with the service manager at Mazda Saturday regarding my car potentially needing a new engine and he informed me that misfires are acceptable on the Renesis, as long as the number is low, ~10-15 per drive cycle... Thought that was interesting.

Borg warner was $31 a piece with a lifetime warrantee, so you will NEVER EVER HAVE TO BUY COILS AGAIN.
even if they are inferior they're free replacemnts so you can't complain too much

The problem with the stock coils is that they wear pretty quickly, let's say 30.000mi, and stay there for at least 60\70.000miles before completely stop working. The issue is not that the coil breaks, it is that it stops working at optimal levels. How can you ask them to replace a coil that is still working?
Agreed that you could buy them as replacements but you would still be driving with crappy coils around for a long time before being able to inquire for a replacement, of a single coil! What about the other 3 that are still working poorly?
Just get the yukon coils and be happy with them for the life of your car

you didn't read the other posts.. Call o'reilly and ask them ask stingray who works at o'reilly. You bring them in, and they'll give you new ones. Period.
I posted the # on page 3 to the o'reilly I called.
So be happy about that
I even told them about the rx8 that said it's fine.

I just got a MAF from them. $70 (the dealer pricing was $170) and lifetime replacement.
I'm willing to bet that after the second or third time in a year that I exchange my MAF, they are gonna modify my warranty.

stingray works at o'reilly. Ask him. Or simply call o'reilly and ask.
If you drive 90K in a year and have to take 30K coils back 3 times to get them exchaned, I think coils will be the least of your concerns.
in oklahoma at least, o'reilly respects the warrantees. I've bought a few lifetime things and went through 3 in a few months

I don't think that the companies back these empirical tests up but that's what i've found with the kits i have installed.
Just some more food for thoughts, maybe not as relevant as it is here since gas is way less expensive in the states.

hmm, only 15k that's a really small number.
yeah it's convient o'reilly swaps out for free, but even more convient not having to swap them out at all.
how long did the yukon's last in your tests?
hmm, I'll have to research it a bit more, but if yukon coils increase mpg I'll have to add it to my comprehensive MPG thread

My first set of yukon coils was installed 16000mi ago, had like 6\7 track days and dozen of mountain runs in 35°c temps. I changed the plugs after 10.000km and am going to replace them again but the coils are still like new
You should pass the 100.000mi mark wthout problems with them and could probably reduce the spark plug change intervals a lot since the better spark keeps them really cleaner.
Just imagine changin your spark plugs every 40.000mi or so instead of every 30.000 which is a good average
