Technically the ignition coils should last the lifetime of the car. Coils have no moving parts and consequently have nothing to wear out. In the hostile environment of the engine bay properly designed coils should have no problems. Apparently the coils used on the RX-8 are prone to failure due, I believe, to inferior quality build. It appears that the insulation breaks down causing the coils to short/ground on the high tension side. There is no way of knowing if or when a coil will fail. Mazda say they have a new and better coil, but I personally cannot verify this and I believe it is early days for any of the new coils to start failing. Time will tell.

mine failed at 8k (or around there) as I mentioned above. The car sat for almost a year before I bought it. Although that should have no impact on it. I bought it with the 8k miles on it and the coils were bad when I got it. Dealer replaced them, huge improvement.

Mine new and improved coils are showing the little white spots at about 15k. I suppected them to be bad again because my car died while at a red light last week. I took it in and am currently waiting on my new engine to arrive. Guess it wasn't the coils that caused the engine failure.

I've been through 3 or 4 sets over the last 52k miles.
However, only 3 or 4 of them actually failed completely on their own and I burned 4 of them by just being bone-headed (I had my ignition control jumpered for 12v instead of 5v - they lasted exactly zero seconds; at least they were already old).
So, I've had half of my coils become marginal and the other half failed, more or less.

I thought this https://www.rx8club.com/showthread.p...t=testing+coil blast from the past was relevant to the converstion.

^^ True, though that is pretty rare. Furthermore, if you really press those coils (hot day, drag racing, etc.) they will probably give up on you at a rather inopportune moment.
Most of the time when it seems like the car "loves" those coils, its because they are the trailing which won't be felt by the driver until they actually do fail and kill the idle quality.

its been a week now that my car has a problem with coils a & c and i havent noticed any loss of power or difference.
Will it take longer to make a difference?

There was a study that a typical new born human *should* have 250 years of life.
but .... who the fuxk actually have 250 yrs of lfe? cuz it depends on TONS of factors.
so just buy new coils. replace them, be happy, just like me.
Your CEL code wasnt even the valid code. make sure u got the right one dude.

thanks but, two diagnostic tools would lie ? or my car went crazy ? :P
now ok, i have the burnt coils symptoms and both DT are saying about the coils/coils circuit, i am convinced that i have to replace them.
