Tony sais. It should last 15 - 20 years minimum.
He said I have a 30 year old truck it still has the same coil.

probably once maybe twice in a cars lifetime. they dont go bad too often

Most people don't bother unless it goes bad. I suppose you could run a voltage output check on it once in a while if you were concerned it might be slightly off peak performance? Otherwise, I've seen some last 20-30 years.
