Can anyone give me an idea of Part numbers for Iridium plugs for the 100KW 4AG? Also, what gap is required (or is the standard gap O.K?).
Oh, and (cheap) stockists of same would be good.
Thanks in advance.
Am using NGK iridium- pn: BKR6EIX (from memory) not sure if the gap of these are correct but u cant play around with them as u might bugger up the tip (as it is very fine).
