Getting ready to change the plugs in my truck, is the recommended plug still 41-962 or is it 41-110? Any help would be appreciated.

I see it is a 2006. If you want to stick to double platinum then the 41-962 is good but the better would be the Iridium plug of 41-985. I see this question was asked back in Sept. Did you decide already?
