Ik31's get my vote too, 071 are good for a trackday car where you want to chuck a new set in every outing "just because" if you are of that mindset, but the IK31's just last SO much longer.
had the denso's in my LAST engine.....(melted, plug tip came off..)..........now use ngk's.........they've been in the car for about 13k with no probs..............i also have 12 071's lying about but the ngk's keep on going
ive been using 071c's and im starting to get a slight missfire again at high revs and boost so i purchased a new set and they've made the tickover terrible, i heard there was a bad batch so this must be why, i noticed the new set had 7f on the side of the plug where as the old set had 6f, so ive re-gapped them and fitted the old ones back in and all is well, but im gonna try denso's next, what sort of money are they ?
i´va had a set of ik27 melting a tip and completly destroying my old engine, ask me if i was mad?
Have used bcpr7et ngk with wery good results on a 330-kit engine.
Am using agps 071c now, but havent mapped for more then 0,8bar so cant say much about them
