I had to buy 8 plugs from rock auto(packs of 4). Still a good deal at $5 each for the iridium xp-5143. I got a new set of MC wires and a MC air filter too. All for about $95.Autolite APP5143 is the double platinum version(PP) for the 4.0l SOHC 2006 and up.
If you don't use double platinum then I wouldn't bother with single platinum.
I saw one listing at rock auto for APP5143 listed as closeout $0.77 each 12 left, but I would double check that they are PP, but even if they are not, 77 cents each! shipping will cost more than the 6 spark plugs, lol, and they will last long enough to meet their 77 cent price.
Yes the iridium are fine to use.
The 4.0l SOHC has a couple of hard to get to spark plugs, so the longer they can last the better, which is why the double platinum can be worth the extra cost.
Installed the plugs and wires and truck is running very good. I needed a new MAF a week ago and between the 2 repairs the truck is running sweet. Pinging and other nonsense is gone!
I have changed easier plugs but not the toughest either. I removed the passenger side tire and inner fender to get at those 3 plugs.
thanks again for the help Ron. trucks seems to appreciate the new MAF, plugs, wires and air filter!
