All, I've got a 2009 328i with almost 100k miles. Original plugs replaced at about 50k. Time to do it again, but confused as to what plugs to order. Bentley manual says Bosch FR7NPP332. Know I don't have a turbo charged engine. My neighbor who always works on his Acura is going to change my plugs so I need to know I'm ordering the correct plugs.
BMW recommends Bosch or NGK. So I would stick to either of those brands platinum is what the oe ones are. But really cant go wrong with either of those brands.
