Hopefully someone can help me out with this. I would like to put NGK IX Iridium plugs in, but I can't figure out which ones I should use. I've seen many threads that recommend using the extended reach plugs which are part # ZFR5F-11 for NGK platinum plugs. Now here's the problem, the part number for the NGK IX Iridium plugs is ZFR5FIX-11 (I'm guessing) for the extended reach ones... BUT on the NGK website they are recommending to use BKR5EIX-11! Which ones should I use ZFR5FIX-11 or BKR5EIX-11? (dunno)
