Frenchy, their volunteering you to do the following:

The perfect heat range depends on your specific driving style as well as quality of gasoline.
Hotter plugs will resist fouling because deposits tent to burn off better.
A higher voltage spark allows wider gap. Modern electronic ingition is much more tolerant of wider gaps. .035 or .040 will probablt not make a noticable difference. In theory, a wider gap will allow better fuel ignition but it would be surprising if anyone could detect a difference of .005" in either performance of mileage.
I think somebody on this thread should do the research...

thanks for the feedback, superdak 05. you the only one that answered my question...at least about the gapping...but,
I didn't ask what our trucks didn't have, I asked what else you had to replace guys.

Did mine couple of weeks ago. Just disconnect the connector and the hold down nut then wiggle the coil assembly a little and lift out . I strongly suggest if you don't have one already get a magnetic type deep socket or one with the rubber internal insert to hold the plug. This is a deep opening. You will not be able to grip the plug with your fingers.

I also have the shop manual on disc and unless the wires which are connected to anti-knock sensors are damaged you do not have to replace them, unlike the previous spark plug cables(pre Gen3).
RE: Spark Plugs update...
+1 on the magnetic or rubber inserted socket for spark plugs... cuz that is one deep hole... hahaha... and yeah I went with .35 on my v6... if you have a v8... IDK... so yeah...
