Plug change - 2001 GT

Silver007 · Apr 12, 2005

Hey guys-

I'm changing out the plugs on my sister's car and she's got Bosch Platinums. The box says "Factory Set Gap" but these plugs are at .065 whereas her car specifies .052-.056 if I recall correctly.

Should I gap these platinums? I've never used platinums before so I don't know. The ground wire is very hard, like you may not be supposed to mess with it, lol.

Any tips on fishing these coils out from under the fuel rail will be appreciated, too.

Hope to get this done before she's back to pick it up!

Also, can someone give me the cylinder layout. There's a misfire on cylinger 4. I think that's driver's side rear?

Platinum plugs do not need to be gapped. The coils come off, you will get the hang of it. Hook your fingers under the coil on both sides of the fuel rail and pull up firmly and gently. Do a search for my tips on changing plugs, I am getting sick of posting the same thing over and over...

I knew I'd aggravate someone with this post, but I'm in a big hurry.

Your overview says to gap them, but above you say not to... what to do...

...and if anyone knows the cylinder layout please advise. I can't find jack on Google.

Sorry... please don't hit me!

Oh no you did not aggravate me... I just have posted it so many times in the last few days. Anyway copper needs to be gapped platinum does not.

Not sure about the cylinders, saw a thread on it the other day should be able to find it by searching.

passenger side rear... all ford motors are layed out this way.. on rear drive bank 1 (cyl 1,2,3,4) is passenger side (rear of the engine compartment if front drive, you know like a taurus etc.) and bank 2 is drivers side (or head facing the radiator, in frt wheel drive)

Subscribing. I need to change my plugs in the next few weeks.

What is the part number of the Bosch Platinum plugs?

hognutz · Apr 12, 2005

I would gap them to factory specs.

Mirrahasmycar · Apr 12, 2005

if it says pre gapped to spec on the box don't gap them, also you can ruin the platinum when gapping platinum pluggs

hognutz · Apr 12, 2005

here is your answer

so if you just have regular paltinums you should gap them to factory specs.

you dont gap platnium plugs. i noticed you said they were bosch. take them back now and get autolite or motorcraft plugs. get copper or platniums. the boschs tend to not run well with the modular motors. the coppers you will have to cahnge out every year, the platniums you can leave in for a long time.

when i do plugs on the COP motors, i pull out all the coils, theres no way to screw them up putting them back in because they are not cylinder specific. also the wiring harness only goes one way. just make sure that you use dialetric grease on the inside of the coil boot, and put anti seize on the threads of the plugs. also do not over tighten, 1/16 of a turn past hand tight is all you need.

Bosch plugs SUCK

If it was my sister's car I would do platinum

If it was my car I would do copper

hognutz · Apr 12, 2005

So what do you guys that say don't gap platinum plugs do when one has the wrong gap?

take it back?

Tylerb59 · Apr 12, 2005

Autolite 764 @ .54

Silver007 · Apr 12, 2005

I knew this was gonna be a dang headache. OK I'll take the Bosch's back and get Autolite platinums and gap them to .054 (midline of Ford recommendation).

Thanks for everyone's responses. I REALLY appreciate it.

Tylerb59 · Apr 12, 2005

No, those 764 are COPPER.

They conduct better but don't quite last as long as platinum. Again as stated above you don't gap platinum!

Tylerb59 · Apr 12, 2005

Here is a good list and discussion:

funny it says right on boshes site you can gap platiunums you just have to do it correctly. So why does everone say you don't gap them?

because people screw them up

hognutz · Apr 12, 2005

hmm. I guess I must be wierd but I would want the correct gap platinum, copper, tinfoil, what ever they are made out of.

It would give me pause to run .065 gap. maybe they run just fine at that. never ran that much gap before.
