12psi Rb25neo - Which Is The Right Plug?

[G_Force]

Hey ppls,

can anyone clear the confusion n give me the right answer. My R34 GT-T running around 12psi(goin in for a tune soon) is misfiring occasionaly. Looking for a new set of plugs as its currently running std plugs i believe. Im after the NGK coppers since most have said that the Iridiums r not really worth the $ when u do the change urself n add the cost up. Is the NGK BKR6E the one? I think this is pre-gapped at 0.8 or do i need a 0.7? Is this the right heat range or do i require a 7 or something colder?

Ive done the searches, read the threads n even asked a question there myself but it seems like there's no conclusive answer. In fact a no. of ppl came out more confused than before. There also seems to be alot more talk about the RD25DET there but im not sure if the RB25NEO requires different plugs. On the NGK site closest listing was the PFR5G-11(something different again) for the GTR. Dont kno if its a R32, 33 or 34. This is pre-gapped at 1.1 n i understand u shouldn't really try n re-gap it down to 0.8 as it could damage the tip and the tip is also no longer parallel.

Just in case anyone needs to know tho i doubt it, mods r Power FC & BC kit, FMIC, turbobak with split, pod, BOV.

Cheers guys n gals.

dunno if that link will work.

Your Vehicle:

8/1998 - 10/2001 NISSAN STAGEA 2500 TURBO RB25DET

Spark Plug Part No.

Recommended Plug PFR6G-11

Iridium Option BKR6EIX-11

I noticed there was no R34 GTT so I went to the Stagea with the NEO engine.

That is the stock (1.1mm) gap, sorry I don't know the number for the 0.8mm ones.

Coppers can be easily regapped to 0.8 from 1.1mm. Iridiums can be too but just need to be more careful. No tapping it on concrete to gap it down.

Yes at 12psi you will need 0.8 gap. If you have to go lower to stop misfiring there is something else wrong.

you can use that plug you quoted, or BCPR6ES. it should come gapped at 0.8mm.

Thanks guys.

I had another look on the NGK site, listed under Nissan Imports is a R34 but only the RB26 motor, plug required for that is the PFR6A-11, couldn't find a Stagea??

Can u just re-gap them with a set of pliers?
