I got my truck with 86,000 on it, and I now am pushing 90,000 and I haven't changed wires yet. I guess that would be up to you and funds

I just looked and thats not correct part number for you. http://www.rockauto.com/catalog/moreinfo.php?pk=69503 6987 this is correct. I am sorry about that. I guess is different from 4.7 to 5.7

Ok I'll have to figure that out. Instead of posting new thread I might as well ask it now since your pretty good on responding fast lol. My truck sometimes when it's in first gear and I let go of gas it feels like the tranny slams, maybe engine. I haven't replaced tranny fluid or anything. Would that be something to do to fix that? Or what does that sound like?

Since you have never changed your fluid and filters (im guessing), it would be a good idea to do that. Sean (snrusnak) did a great write up on this. Here is the link http://www.ramforumz.com/showthread.php?t=92056

If you continue to have the transmission issue I'd get a hold of member transengineer, he could maybe help diagnose it for you.

99% of the time the stock/oem plugs perform the best. Ignore all the hype from the fancy aftermarket plugs and stick with oem, will save you a ton of headache.

I'm not sure what was stock on the 2007 and older 4.7L. I know on the newer 08+ but it's not the same. The new engine uses 2 plugs per cylinder, both different, and the old engine has 1 plug per cylinder. I'd assume it's not the same as either from the newer engine.

Should be in the manual or something...

But if the stock plug is say bosch copper heat range 8, then going to a ngk copper of equivalent heat range is fine yes.

Be carefuly, all companys heat ranges are not equal, and some are reversed. There is a chart for cross referencing heat ranges, can probably google that.

My main point was don't go to an E3, or dual electrode, or tripower, etc plug. Use whatever is stock, it'll perform the best.
