Spark plug differences?

[Gravija]

I am going to change my spark plugs because upon startup on cold days, the car just dies unless I hold down the gas for like 15-30 seconds.

I searched and came up with using the NGK PFR6B-11 or PFR6G-11
One poster mentioned however using spark-plugs.com that there are iridium plugs, are these better than the platinum plugs?

Would I be able to use them in my car?

Thanks

Iridium or platinum will work fine. I doubt they are the cause of your problem though. I'd suggest cleaning your throttle body and checking the idle air bypass valve.

I use the NGK Iridiums...the difference may be shorter overall life of the plug compared to the Platinums..traded off for better overall performance of the Iridium compared to the Platinum plug..really comes down to your preference..no problems for me using the Iridiums..Ive used them for a few years now

WHEN I WENT TO THE DEALER TO GET THE STOCK PLUGS THEY GAVE ME THE IRIDIUM. AND THAT THEY SHOULD LAST ABOUT 60k MILES. YEAH THEY ARE EXDPENSIVE BUT AT LEAST I DONN'T HAVE TO REPLACE THEM THAT OFTEN AND AT THE LONG RUN IT SAVES MONEY.... I BELIVE THAY ARE ABOUT 12-15 BUCKS A PIECE. BUT WORTH IT....

Please don't type in all caps.

The stock NGK platinum plugs are supposed to be good for 100k miles. I pulled my original plugs after 133k miles and they were all really fine. I replaced them, anyway, but I don't expect to for some time again.

That's fine by me - that was a pain in the ass.

I'll second the comment on the Bosch plugs, I've replaced many of them that were short-lived. Especially avoid their +4 plugs, more electrodes = too much spark shrouding.

Just read your info on plugs.

The stock plugs are the PFR6B-11's. I asked a local place about the Bosch plugs and it was recommended to stay away from those if I want the engine to run properly.
