i think the gap is 40 check under the hood it should say. youre not supposed to deviate more than .008 from the mfg gap.

 

but if i just get the plugs meant for my truck all i have to do is screw them in right.....?

 

Should be, its a 4.7 right? Hemi has 16.

 

Check the gap on the plugs before putting them in. They are never exactly gapped properly & many plugs fit other makes/models.

Make sure you blow the trash out of the area around the plugs so none of it drops into the cylinder. The back four are a challenge to get to. I think the '07s don't have plug wires, so just take the coil packs off an' go for it. The time range to change all sixteen is 1 1/2 to 3 hours.

 

Don't gap iridiums. They are ready to go.

 

Any plug can have the gap altered in shipping. Coupla good bumps is all it'd take.

 

They come packaged with protective sleeves so that the gap can not be altered during shipping. When adjusting gap on an iridium plug, you have to use extreme caution. They are not like gapping your regular copper champion plug. You can damage the plug if not done right.
