M30 spark plugs

[be34st]

I remeber reading somewhere that these M30's are finicky about their spark plugs, which are the bst ones to use in an M30?

My gas mileage seems to be unusually sucky and I think it's time for some major maintenance to be addressed.

Bosch coppers or ngk v power coppers i forgot the part numbers but should only be one type. No need for platinums or anything special. Make sure to gap them to oem spec as well.

B34: Bosch WR9LS (BMW# 12 12 1 279 599)

B35: Bosch 7909 WR8LC+ (BMW# 12 12 9 061 869)

They do NOT like platinums.
