That's two steps hotter. Most use at least one step hotter if they have the nutz to violate the owners handbook. Two steps means the Previous owner or his wrench had "Balls as big as pickle jars"

That means your plugs may last 5 times as long as the average 930 owner who throws his plugs out because they are fouled. If it is a street car, I wouldn't think twice.
