spark plugs ? reg vs plat

[mr-mike]

what do you guys think are better in high milage 4.6 regular or platium , years back when they first came out they fouled very easy & didnt give the hot spark of the regular plugs .........................

If you are willing to change your plugs every two years then use copper, it has a hotter spark. Use Motorcraft AGSF-32C.

If you want to change them every 60-100k use platinum. Use Motorcraft AGSF-32PP.

There are a lot of tips/tricks to changing plugs, do a search to find them.

Do not use any other brand of plug than Motorcraft.

id go with copper plugs way cheaper and its not a bad idea to change your plugs regularly like 30k

if you dont drive much and put on low miles, get the coppers. if you drive a ton and will prolly forget to change them, do plats or iridium.... i like iridiums i have now... good stuff, pricey... power of copper and longevity of platinum... cost of a small airport

As was already mentioned. Coppers have a hotter spark. Autolite's are $1.39 per plug. Its pretty simple to change your own spark plugs and it only cost about $13 every 30,000 miles. Let us know if you have any more questions.

Just to mention, I had a shop tell me that platinums start to lose some integrity by 40-50,000 miles. Take that for what its worth, but overall cost/benefit coppers are the way to go.

Motorcraft and Autolite spark plugs are the best for are cars period.

thanks guys

I'm going to put in a set of copper this week I'll let you know if I feel the difference should have asked "whats the best gap" ......................

.054 if you are mostly stock

I beg to differ... NGK are great plugs.

What if you are heavily moddifed N/A?

 

[Kilgore Trout]

I know that FI and nitrous guys use different gapping strategies. That's all I know, sorry...

 

[CanadaStang]

If you're not heavily modded you may as well stick with the factory recommed platnums. The slight difference in spark between the two is not an issue with anything other than a fully modded engine.

I thought using copper for hotter spark was only suggested on the non-pi GTs I dont remember why i am thinking that, maybe because the PI GTs have COPS ignition and the non-pi cars have coil packs?

Hmm crap now i can't remember. Did the non-pi GTs have COPS too? LOL

 

[Kilgore Trout]

So the laws of physics only apply to non-pi? Copper is copper regardless of what engine it is in.

Yeah i just thought i remember hearing something like they were better in the non-pi car over the 99+

Whatever though

I have played around with my gap several times.....the reason I asked is because I run platinum plugs and tried gapping from .50 to .60 and My car produced the most power and TQ at around .51. The car has all the bolt on's and then some.....plus the idle was much smoother. My buddies car we set at .55 and his was pretty much stock and it ran better with a slightly bigger gap.... Just wondering why?

You want to run the widest gap possible before you have issues, if yours likes .051 the best, then that's what I'd stick with.
