creativefleire Posted January 19, 2012 Share Posted January 19, 2012 Can someone here please tell me what's the best spark plugs for me to put into my '94 R33 GTST. The ones that are recommended from any auto shop are the Platinum PFR5G-11 2647 ones. But someone else told me that these prg5 plugs are way too hot. and will detonate and cause other running misfires. The Nippon Denso ones apparently are better??? Is this true? And where would I get these Nippon Denso plugs from in Perth? Link to comment https://www.sau.com.au/forums/topic/388843-spark-plugs-for-r33/ Share on other sites More sharing options...
boostn0199 Posted January 19, 2012 Share Posted January 19, 2012 Just stick with ngk coopers prpven to work well on rbs and cheap. Rule of thumb if your running up to 12 psi use bcpr6es at 1.1 gap if over 12 psi use bcpr7es .8 gap.

creativefleire Posted January 19, 2012 Author Share Posted January 19, 2012 I'm running up to at least 15 psi. It's in desperate need of a tune so may run higher. Sorry, but not sure exactly what you mean by "8 gap" ?? Where can I find these bcpr7es plugs in perth?

89CAL Posted January 20, 2012 Share Posted January 20, 2012 bcpr7es and gap them dwn to .6 .7 Shouldn't need to go that low. i run .8 gap with 18-19psi Unless your coils are stuffed but then your just band-aid fixing it Link to comment https://www.sau.com.au/forums/topic/388843-spark-plugs-for-r33/#findComment-6196693 Share on other sites More sharing options...
