Great write up
My key takeaway is that I should stay with the NGK's for my R56 Cooper S if I have not crossed Czars A rule of thumb - 'one heat range colder per modification or one heat range colder for every 75–100hp you increase'. Correct?
Or are there some copper or silver tip options that might give me a little more bang for my buck albeit more frequent change outs? -

FYI - the NGK BKR6EQUP and BKR7EQUP are no longer Iridium tipped. They are now "Laser Platinum" If sticking with an Iridium tip is a necessity you'll need to move to the BKR6EIX and BKR7EIX plugs.

I've been using NGK BKR6EQUP plugs in my MINI since the first plug change I did in 2007. Those plugs have always been platinum, not iridium.
Hope this helps somebody.... -

It's about time for me to change plugs again... my current set of NGK plugs (BKR7EIX) did not last quite as long as my previous set. Possible reason might be because the engine is getting older.
In anycase, is there a comparison with other manufacturers' plugs other than NGK ? I know a lot of MINIacs have recommended Denso or Brisk plugs but I have not actually seen any reviews anywhere of any benefits longterm wise other than the initial "I put these on and they were much better than the NGK's". Given that they replaced old worn plugs with brand new ones, I would expect that kind of reaction. If nobody offers a better long term review, I will probably just go back to a new set of my current plugs. Or even go one more range colder as I noticed I seem to be getting a lot of misfires of late. Probably time to replace that original coil pack too. -

Just keep using the NGK plugs you mentioned.
I used Brisk plugs for a while and they did not last as long.
