Oh, I think BKR7EIX's are supposed to be pretty sweet - cue more knowledgeable person to come along and correct me

yes, more power requires cooler running plugs (which is denoted by the higher number)

They're the iridium version of the 6ET's. Fine for a relatively standard car - if you're running more boost than standard, 7's are recommended.

I know it's an old post, but I'd like to add NGK part numbers, sometimes search for BK*** codes doesn't yield results.

BKUR6ET - NGK Stock No: 6437, "Standard" range - copper plug, 3 electrodes
BKUR7ET - NGK Stock No: 7873, "Standard" range - copper plug, 3 electrodes
BKR7EIX - NGK Stock No: 2667, Iridium IX Range
BKR8EIX - NGK Stock No: 2668, Iridium IX Range

Are there any benefits or downsides on running colder (BKUR7ET) or colder Iridium (BKR7EIX) spark plugs on stock or nearly stock (eg. remap up to 1.2bar, without other mods) 20vT?
- lumpy idle?
- worse mpg and/or emissions test?
- longer lasting?

Any experience with NGK Platinum (roughly same price as Iridium)?
