What spark plugs?

[BurningRubber]

Might get around to changing them tomarrow, along with the fuel filter.

Which brand plugs are best for the 2v?

And for the fuel filter, I need a fuel line disconnect tool correct?

NGK-TR55's and yes....

Would AutoZone or Advanced carry them, or are they a dealer thing only?


Sick Roush by the way...

Those stores and Napa should have them in stock I believe. I got mine from a local Napa.

Thanks....

Same heat range, different manufacturer. The ones I suggested are made by Ford, the other NGK. One plug is as good as another. Buy whichever one you can get cheaper. The NGK's have a "V" pattern cut into the center electrode to improve spark propaganda, but it's mostly gimmick. You can get the same effect by filing back the ground electrode to the middle of the center electrode on a regular spark plug, but even then the benefits are minimal, if any at all.

Ok cool, thanks for clearing that up.

....and Platinum Plugs (if anyone should decide to suggest them) are for guys who like to spend money. Their only benefit over the copper ones is longer lifespan. Platinum plugs are good for 160,000km, where the Copper ones should be changed about every 60,000km. Sounds good on paper, but who do you know that waits that long to change their spark plugs…..regardless of the type of brand? The Copper plug will burn a little hotter and therefore cleaner. Meaning they will perform better, while maintaining better fuel economy and more controlled emissions levels. Not to mention they’re about 1/5th the price.

I plan on copper plugs. Platinums are too expensive (like you said) and I wouldnt want to leave them in there for that many miles anyway, haha.



Another question though... Ive read a bit about the 4.6's love to spit plugs out of the head due to them being too tight, or too loose. I dont have a tourqe wrench, so whats the best way to get them tight without damaging the threads? Get them threaded by hand, and tighten untill snug, and a partial turn more?

Motorcraft or Autolite plugs are the way to go on are cars.

Yep.....just do a visual check on them every time you do an oil change or so, to make sure they haven't worked their way loose.

And the coil packs... just unbolt, and remove them?

 

[Gearbanger 101]

Sure....but why would you remove the coil packs? Are you changing them as well?

 

[BurningRubber]

Ahh, crap my bad. I mean the coil on plug deal, they lift up and can be place to the side to get to the plug, right? Im working on a 2000 GT.


And I got Autolite 764's... I asked for copper relacment plugs for a 2000 GT and thats what they gave me. Stupidly I forgot to write down the part numbers before I went to get them.

 

[BurningRubber]

Done... started about a half hour or so after the last post or so. But I took my dear sweet time.

It was easy, didnt have any trouble with space, even on the passenger side.

I was shocked when I pulled the old plugs... They were all white and somewhat ash-like... so I do beleive its is, or has been running lean. The old plugs were Autolite Platinums, but it really looks like they could have been the origional plugs by the shape of them.

The 764's I got were the short thread, and that made me a little leary, but the old Autolites were also so I felt a little better about that. I will keep my ear out for ticking, and retighten them after some mileage.

Butt dyno picked up a good bit of improvment. Alot better response, and it helped alot with the slight cold start bog I was having... also pulls harder and smoother.

Fuel filter is next...

Plugs and fuel filter are both great things to do and will improve gas mileage

Hope so, I got 23.1 or so mpg on my best tank so far. Thats mixed city/highway and I couldnt keep my foot out of the gas for at least part of the tank, lol.
