I just got new plugs for my 2015 S 550 4 matic. Bosch ZR6SII3320. Amazon packed them with some other heavy stuff and they got beat up a little and I want to make sure gap is correct. Says they are pregapped , but now I think I should check as the boxes were all crushed.. Anybody know the correct gap?

Thanks
Super response. I will gap all at 1mm.
Very good info on plugs

Send the bashed up plugs back!!!! Spark plugs are easily damaged by hard impacts. The ceramic insulators and seal to the steel shell can be damaged and invisible to the eye. Not worth the risk IMHO.
