Thread: PFR6G or PFR6B?

I ordered some tune up parts from Gspec performance. The plugs Greg sent me are NGK PFR6G-11? Did I get the right spark plugs for my car? 1998 Nissan 200SX SE-R. I thought the standard plug was PFR6B-11?

NGK part finder http://www.partcat.com/ngk lists PFR6B-11, however should be interchangeable,

I saw those links when I was doing my research. Well I guess I’ll be using them then. I just wish I knew what the difference is between the two plugs.

From what little research I put into it, I saw something about the electrodes in the center being different. One is solid platinum and another is platinum plated. Probably the more expensive model being the one with solid platinum electrode.

I would use Iridium. I changed to them and noticed the best difference ever in a spark plug exchange.

I’m going to use these for now. Got that damn smog test coming up soon.

Thanks guys.
