I like to change the cap yearly as a matter of practice. A couple of weeks ago I was doing some investigation for what I thought was a carburetor problem (Webers) but the symptoms turned out to be the advance weights binding and sticking on the pivot pins (light springs). I cleaned and replaced the weights & springs and all is well. I've had the MSD Pro Billet distributor for about 10 years now and really never had given the working internals much thought previously, as I am for the most part in a dry weather climate without a lot of humidity. However, the magnet was pretty rusty (surface) but to date has not cause any reliability issues. I will probably replace the pickup and reluctor this Winter.
MSD's products are well engineered.
