How long do Miata coil packs last?

I'm at ~85k and mine are just about dead, they probably won't last another 2 or 3k miles.

Just wondering if this is normal.

As far as I know mine are original and they still work fine at 126k. Of course I could be an exception.

How do you know they're "almost dead"?

They barely fire when they're cold and it's getting progressively worse. The spark is very weak, my plugs are gapped to 0.25" and I'm still getting spark blowout.

~4-5k old. Not them. Plus, I know what it feels like when they're going bad, it's happened to me before.
