Question about RB20det sparkplug fitment and interchangeable?

[rb20jdmizzle]

Just a quick question. I know that the RB20det used the NGK PFR5A-11..and the NGK IRIDIUM BCPR6EIX-11. But have anyone used the NGK PFR5G-11 PART#22401-1P115 (which is for turbo)...because i found the NGK PFR5G-11 is similar and identical to the NGK PFR5A-11.

I was using Autolite APP3924 and 3923 at one time.

Thanks Themadscientist. Reason i asked is because i went to Couresty Nissan and they don't had the pfr5a-11....and they tried to give me the PFR6B-11 which not even close!!! and so i take a look at the PFR5G-11 and they are just similar to the PFR5A-11. I will try it out and let you guys know how it gone.
