I'm wondering what spark plug heat range you're all using on your boosted Rovers?
I've been using NGKBPR8ES for a few years but they seem to be running too cool in normal driving to & from work, ultimately shorting out on the centre ceramic insulator.
I've bought some 7's but am a little worried they may cause detonation when I do push on a bit.
