They are alive and they like to screw with your head. Example: I had one of those damn MSD caps with the little stupid ball come apart at the Fing in 2003...first time KMP184 made an appearance. Decided I would never let one of those put me on the side of the road again and that i would carry a spare.

I've had to replace the unused "spare" twice just because I wasn't sure if the graphite (or whatever) had a limited lifespan.

I have no doubt that if I stopped carrying the spare, the car would giggle a bit as it wound down and left me sitting miles from nowhere.
