Any chance those were knock-off Bosch spark plugs? Lots of NGK Chinese knock-off spark plugs floating around but you don’t hear of it being a big problem with Bosch. There is market, they are expensive, so there must be some fake Bosch plugs floating around.
Maybe give Bosch customer service a call and ask how to identify fake Bosch spark plugs.
