I mean it is absolutely not a question of money it's more of a is there any disadvantage going for a colder spark plug?

The way an inexperienced person like me is seeing the situation right now is the colder the safer, so if you could clarify why it's not worth getting colder plugs maybe that would help.

Trust me, on N55 x drive you are fine on OEM coils and plugs with FBO and tune.

The only time you should consider 1 step colder NGK plugs is if you have a hybrid turbo.

You're fine if you go with 1 step colder or OEM with FBO + tune. Just depends on what you just feel like doing.

I already gave my experience that 1-step colder is good.

You replied to a post where I am saying that there is no need to pull your plugs back out to gap them down smaller. Two completely different things.

Since I see lots of reference to "one step colder" with no reference to part numbers, I wanted to point out that on the BMS website it's all relative to the stock N54 plugs.
So the: "NGK 5992 1-Step Colder Spark Plug" is actually the same heat range as the stock N55 ZR5TPP33S plug.

One step colder would be the NGK 97506 N20 replacement ones.

Yeah I'm going stage 2 and understood that stock plugs were fine.
