I am changing out my standard stat for a 71degree item, the proposed benefit of this swap being reduced engine block temperatures. Given this change (which appears to be backed up by Hartech trials) should I be changing to a hotter grade spark plug? Car has the recommended Bosch FGR5KQEO in it at present, the hotter spec is an FGR6KQE which also appears in various places as the recommended plug for the 01-05 3.6 Carrera.
Any experience welcome, I'm doing all the coil packs as well and don't want to have to delve back in here for a few years if at all possible!
