Picked up Bosch oem plugs from O'reillys (sold for 1/2 of what it goes for at Tischer)
I had 1 Plug from Tischer to compare it to. They look to be the exact same thing minus
the label and the notch on the tip. see pics:
BMW's with the thinner head.
Question is, Are all Bosch plugs part #FRZNPP332 pre gapped from the factory like Tischer's is or not?
