james1 Posted February 8, 2012 Share Posted February 8, 2012 (edited) well basically i know i should be getting the 7 heat range plugs. however just trying to determine which ones, as the fitment guides on ngk having nothing for the gtr's. just a quick model number even of what you guys use will help me to know which ones are right. doing around 320awkw r33 gtr Edited February 8, 2012 by james1 Link to comment https://www.sau.com.au/forums/topic/391079-which-iridium-plug-model-numbers/ Share on other sites More sharing options...
blind_elk Posted February 9, 2012 Share Posted February 9, 2012 as the fitment guides on ngk having nothing for the gtr's.You obviously didn't look too hard. ngk.com.au comes back with a PFR6A-11 (standard for all GT-Rs) equivalent to BCPR6EIX-11.If you are running a few more ponies, then you probably need a 7 heat range, and maybe close the gap a bit (maybe 0.9).
