I guess any plug can rust. I am starting to lose confidence in Bosch though. Rob Grady will not recomend the Bosch Platinum plugs anymore. He said he has seen where they "blow-by" or leak between the procelin and the steel shell. Maybe the standard Bosch are OK, just don't let water get into the wells and rot the plugs? The steel shell is supposed to be plated to prevent corrosion, maybe it just is not enough if water lays in the well for a long time. This is just another reason to change some parts once in a while or every 20 years if you use the car or not. No car likes to sit and not be used especailly outdoors.
