nuffsaid Posted January 5, 2006 Share Posted January 5, 2006 (edited) Hi all Have searched and it seems like everyone uses different plugs. Any R34 GTT owners out there with experience in using various spark plugs? Id like to know what you are using and what you recommend as I have a service due soon. I hear that the standard ones are fine, especially if you replace them regularly enough because they are cheap. People have also said that the iridium ones are a waste of money, but perhaps they have performance gains? Whats best? The general consensus is that a 0.8 gap is best, especially for higher boost applications. However will 0.8 gap also be fine (and better than 1.1 gap) for stock boost? Thanks in advance.

nuffsaid Posted January 5, 2006 Author Share Posted January 5, 2006 How much boost is more boost? How much power is more power than stock? I guess those are 1.1mm gapped? Alrities Thanks SW20 Anybody else got any opinions?

Tosh Posted January 5, 2006 Share Posted January 5, 2006 Sorry... your right, I was a bit vague A stock R34 RB25 shouldn't be running more than 13 ~ 14 pound anyway so anything up to there. I'd run the 6's and go to 7's if you find you keep fouling them Link to comment https://www.sau.com.au/forums/topic/100730-spark-plugs-for-r34-rb25det/#findComment-1838694 Share on other sites More sharing options...
nuffsaid Posted January 5, 2006 Author Share Posted January 5, 2006 Cool, perhaps 6's with 1.1mm gap should be fine then. Cant really expect any performance on plugs.
