I'll be looking at doing the plugs soon - I did wonder why the NGK's are so much more than the Denso counterpart (£30 vs £12):

... Especially as APR themselves recommend them too:

Not one to skimp on running a car at all, but when it's £240 vs £90 for uprated plugs that are both being recommended, would be nice to know why the NGK's are worth over double?

Was just from a quick Google for the Denso's and it came up... looking closer it seems to be more targeted at the S6/S7 upgrade but can't imagine they won't work as well in the RS?

I’m sticking with the NGK stuff for my APR stage 2 as haven’t been told otherwise..

Now confirmed from APR US that they recommend NGK Image
