Lightbulb 2006 4.7L V8 - Best plugs after 100k miles?

The commander just punched passed 100,000 miles last month...

I have an '06 4.7L, V8 and I need to know the best plugs/best experiences people have had with Spark Plugs in the higher milage Commanders...?

I know there has been discussion about using OEM plugs, otherwise the computer may throw error codes.

Any other things I should know?

I am looking for some insight, here in April 2013, after people have had their Commanders for several years...

Thanks in advance for anything anybody can offer!!!

I use Autolite Iridiums in my 06 4.7 and never had a problem. Gas mileage went up about .2

I installed some Denso platinum TT and they due there job, but I did not see any mpg increase at all. So I guess you might want to try something different and see if you get any improvements. But if you have never changed them before then I think you are definitely going to see an improvement no matter what you install.
