Spark Plugs For R33

[creativefleire]

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?

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.

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?

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

Yeah i got them at .8 on 18 psi its fine aswell.

I'm running about 15 psi at the moment. Where can I get these bcrpr7es plugs from in Perth?? Do I need to go to a tuning place to get these specific plugs from??
