Yeah I read BMW doesn't recommend anti-seize but after pulling the plugs out, there was a fair amount of build up on the threads that made them slightly tough to remove. The plugs were otherwise spotless.....So I put on just a smidge of anti seize on and when I say a smidge I mean a smidge. I know the debate still rages about with or without. I'm no expert so I tried to error on the less side
