So I"m placing in brand-new plugs right now...need to void them come the exactly specs.I"ve obtained a couple different gap numbers to walk by. Mine Haynes/Chiltons claims .062-.068. Then I"ve likewise seen various numbers on various forums. The plugs ns bought are Autolite Platinum AP5144. Right currently the plugs room gapped at about .048.So those who have actually a factory publication that says what the void should be, please post it. Together a reminder...my van is one "01 4.0L SOHC.THANKS!!ShaneEDIT: WHOOPS!! Looks favor I"m logged in on my brother"s account!!
I just put those plugs in mine a few months ago. Initially, the truck ran beautiful, but now is beginning to idle rough. Only has about 5,000 miles on them. Someone called me the wide gap is make them last 100,000 miles. The sticker under my hood said .062-.068. It was recommended to me come go with around.054 and also replace them about 40,000 miles. BUT, favor I said, i don"t like the way the van idles now, so i will more than likely pull them this summer and replace through Motorcraft dbl plats.
I can"t psychic if this uses to the 4.0L or not, yet the 3.0L specifies double-platinums because one financial institution is "reverse" firing, guideline to electrode instead of electrode to tip.I can"t see a factor to space them any other way than specified by the decal under the hood.
yeah i"d just gap em between .062" and .068". If friend much much less (like .048" because that example) you *might* lose a bit of gas mileage because of a slightly smaller spark/less efficient burn.
stock gap on the sohc is ~.065. I changed out mine plugs recently and also gapped them come .050, I havent noticed any kind of decrease in purpose of use or performance.
well the share plugs on the 3.0 space .042" to .046"... I initially regapped to .032" v the juice, and noticed about a 1mpg loss. (in my case, most likely a combination of the small gap and the enrichment fuel being included to the n2o injection)
ALrighty ya"ll....I gapped them to .065 and am throwing castle in tonight. And, if I have a negative time through them, I now know exactly how to traction the inner fenders and also swap the plugs.....semi-easily.

I provided the bosch platinum 2"s....as in 2 equipment electrodes v zero gaping required. They space absolutely perfect!
.065 gap, the was the iridium plug and that turned out to it is in to much gap for the plug to handle. An additional thing was the the reach reportedly matched that original Motorcraft plug
.708" however the Motorcraft plug supposedly had an extensive tip and the Autolite does not which ns still think is why lock don"t it seems to be ~ to organize up as declared in post above as they are running cooler. Ns then put in the Bosch +2"s (4305) and the van ran good but gas mileage was down. Ns pulled the plugs ~ a couple of weeks and the amount of carbon fouling to be unbelievable - just reason the made any type of sense when again was the they were also cold the a plug. I then ended up through some NGK TR55-IX"s, not correct again. Lastly NGK TR55-1IX"s, let me say the the usage is ago up, strength is ago up, throttle an answer is an excellent - really impressive so much to speak the least. It runs great! probably should have actually just acquired the Motorcraft plugs indigenous the dealer and called it day looking back. Over there is so much wrong spark plug info on the internet for the 4.0L for 01 thru 03 and even 04 it"s simply stupid.
