BOSCH it is! (N55)

Anyone know if BOSCH is better than NGK?

I've used NGK plugs on all my vehicles, non-bmw/bmw's... no issues at all

Ultimately I think people have success with both brands. In my research I think there's just more room for error with the NGK. Some people swear by them so who knows. I'm pretty sure when I did my plugs on my E46 M3 they were NGK.
