was there that much of a need to be rude? ya I was lazy, that it's right there.There is no way you should depend on the factory to gap your plugs. Think about how many different cars the plugs you bought may fit. Also, think about what has happened to those plugs in transit since they were manufactured, boxed, shipped (at least two diffefent times), and then handled how many times at the sellers store. I'd bet that you didnt use anti sieze on the threads and dilectric grease on the wire connectors. If you dont have the time to do it right, why do you have the time to do it twice???? You are either lazy or (well you finish the sentence).
wow, I had no idea the situation was this serious.....you need to spend a few hours reading some of the sticky's at the top of the 4.6 forum, as well as searching google til your fingers fall off your hands...you're not quite ready to be modifying a 4.6, let alone posting these kinds of topics in the 4.6 engine tech forumI don't think this has aluminum heads, and my threads were fine, I'm actually certain it has regular steel heads.
ummmmm.... I didn't know spark plugs were such a huge deal.wow, I had no idea the situation was this serious.....you need to spend a few hours reading some of the sticky's at the top of the 4.6 forum, as well as searching google til your fingers fall off your hands...you're not quite ready to be modifying a 4.6, let alone posting these kinds of topics in the 4.6 engine tech forum
still, what's with people being so harsh around here?
some people say that their mn12s wont run that well on bosch....i personally can't say since i never ran bosch's in mine.....but yes the rest of your info is pretty much accurate.....and also dont forget that its usually the copper plugs that are available in a wide-variety of 'heat ranges'; the cooler heat ranges being the ones that allow more timing advance in the eec's tuneOn the brand of plug, I have heard that it's best to use Autolite Double Platinum or Motorcraft DP (same plug, different name), bosch (I think on that one, not sure, have heard that some cause issues) and NGK. Copper plugs transfer energy better, but won't last nearly as long.
I hope the cavemen don't see this, they got pretty upset with those geico commercials.....We're just tired of people not doing their homework before asking some pretty simple questions that have already been answered many times in many places here either in the technical articles (There's a link to them on the home page of this site) or in the stickies at the top of every section; and if that fails there's always. :search: Yes, search. Not just here but also on the search engine of your choice!
If, after doing all of that research you still can't find the answer to your question then pose your question in a thread that might closely relate to your query before starting a new thread.
I honestly don't believe you've read "Tons" or you would have known that these engines have iron (aka steel) blocks and aluminum heads and the need for properly gapping your plugs.
I found the following after entering "properly gapping plugs" into Google.

It's so easy a Caveman (or in this case a Trunk Monkey) can do it.
I'm not worried about longevity here, I just needed to replace them, When I get some cash next, I'm going to get some top shelf plugs.On the brand of plug, I have heard that it's best to use Autolite Double Platinum or Motorcraft DP (same plug, different name), bosch (I think on that one, not sure, have heard that some cause issues) and NGK.

Don't think I disagree with you, I can't stand those idiots posting in their freakin' txt language. I do search and I do read lots, sometimes bits and pieces of things I've read slip into the back of my memory or get mixed up with something similar I've read. So I have to apologize for that, but I certainly accept corrections and constructive criticism. and sometimes I simply can't find the right combination of search terms.well posting in the wrong forums will clutter them up, so when someone is told to search, many irrelevant threads may come up and thus discourage the new forum user from searching anymore....and spark plugs (in general) are certainly not specific to the 4.6/5.4 modular engine
as for being "harsh", it's more about being 'firm' as to what goes where....if it wasnt for tccoa i wouldn't know 90% of what I do about my car...and lately, as in the last few years, there's been an ever-increasing "wave" of new users that can't spell, type horribly incomprehensible garbage with ludicrous internet lingo/slang, dont wanna search, yet they still wanna be helped out with their pipe-dream goals and aspirations
what do you mean by 3 threads?Any plug that has a skinny center electrode will wear out four of them in around 10k miles, due to the way our ignitions work; that's why the Bosch plugs don't last.
The center electrode on mine were worn below the ceramic, lol, and still mostly firing.
BigJohnny, the worst thing about our heads is that there are 3 threads in the head some years. I'm pretty sure that includes my 96es... but does not include the dohc motors.
These cars sometimes blow plugs out after a plug change, due to damage.
That is why everyone is telling you to use antisieze. I use it on everything I take off except suspension and brake parts. (which get covered in loctite.)
Coating the plugs and boots with dielectric grease will make your plug wires last longer; it's much cheaper in the long run. And it helps with a blown intake gasket, lol.
