Timing belt job soon, What spark plugs should I use.

[tidus888]

Hi guys, I will doing my timing belt job next week and just getting the parts in one by one right now. I am just wondering that sparkplugs I should run on my car. I know the oem uses NGK PFR7Q, but what other alternatives are there as I heard they ain't the best. And plus winter is nearing, dont want roughy idle/warmup in the freezing weather! Thanks in advance. btw it's for my c5 rs6

Someone please bring on winter. It was 97 today and I cant take much more of fall.

Some have tried Iridium with mixed results. I have stuck with the OEM plugs and dont plan on changing.

OEM NGK PFR7Q, end of story.

Well, don't flog me for this but, I put in Autolite double platinums about 9k ago. They have been fine so far.
