Thats what's been recommended for the last 19 years of the Explorer.
And about 8,659,321 times on EF.
i run bosh platinum irridium plugs-$9.95 each with 8mm taylor spiro pro wires.works and runs great!
LOL give it some time, you'll be back to Motorcraft/Autolite in a few months...
Tried bosch, they lasted about 3 months and then ran like crap, it was just a huge waste of money. So now I buy the "cheap" plugs and everything has been great for over two years.
not sure how you can say the plugs are working well if your truck is throwing codes. That means your engine is not running properly to begin with. If the cost of the plug was a direct measure of it's quality then everyone would be running those super duper double v grove ultra spark barn burners for 15 bucks a plug.
for both 171 and 174 I would
1) check fuel pressure, your psi could be low
2) look for vacuum leaks
3) replace the fuel filter
4) clean the MAF
a single electrode platinum point will out preform any double, triple,quad v-grove or any other fancy stuff you find out there. everything else shrouds the flame front and could cause alot of unburnt fuel in your cats.

like i said, im not saying every one is lieing. but what i don't understand is why do they make these double, triple platinum irridium plugs that cost $7 and up each? i mean they gotta be some what good. i saw these one plugs(can't remember the name) but they cost $25 each. im not saying the motorcraft and autolit plugs are no good. its just you would think these advanced expensive plugs would out perform the others.
I guess you think slick 50 is a miracle cure as well? At $25 dollars a bottle it must be awesome.
It goes like this
Marketing hype + High Cost = Buyer confidence (it must be good)
I could list 20 products that all use the same tactic to sell. All you need is to have a race car driver endorse the product. I'm not trying to be difficult or make you look stupid. Believe me we have all been there, because seeing is believing. All I am saying is don't buy into the marketing hype.
You may also have clogged injectors causing the pulse width to be shortened which will cause less fuel/ lean condition. Or maybe you have a dead spot in your TPS, or a bad Temp Sensor. Actually there could be a lot of factors that will swing you to the lean side.
well my next set of plugs im probably going to try the autolite plugs. i only got like 35,000 miles on these bosh plugs. what is the best plug between the 2? the motorcraft or autolite? and should i get platinum on either one?Exactly- just because a plug is $10 doesn't mean it's good. Will it work initially? Probably. Will it last as long as a stock replacement Motorcraft? Probably not.
It's just an overwhelming majority of people that have had plug problems have been running Bosch plugs. Not to say either- that a lot of people may be running them that have no issue with them- so they probably don't post on the EF. But, the vast majority of plug issues seem to be with Bosch plugs, that's all.
I just don't know of anyone that has posted a "damn I wish I hadn't put these damn Motorcraft plugs in, what a waste of money..."
