Is the engine "stock"? Or does it have better heads, cam, etc.? Supercharged? Nitrous?

Gotta have more info.

If you're naturally aspirated, Motorcraft is best. If you're wanting to drop some $ on them, you can get Splitfires. I don't think the Motorcrafts are any better, although I'd like to hear some arguments.
If you're running a power adder, stay tuned for others' posts.

im not very experienced with plugs and the 5.0, but there is a new spark plug on the market, it might be worth a look see.

Cool, thanks for all the replies. It is a stock engine and the only thing on it
is a cold air system, high flow cats and H-pipes. Thanks again for all the help.

Good old 5.0s seem to love Standard copper plugs! None of the high tech expensive jazzy plugs.
Exactly... until you get into the power adders. I think this is true for all OHV V8s, the real muscle.

ive actually read that because those fancy plugs are made of platinum is the reason some older cars dont like them.
the older ignition systems simply dont have enough juice to get a good spark off of platinum.
the article recommended thart all cars made before 1993 avoid the platinum plugs

So they might actually be worth a shot if you're running an MSD, or some hotter ignition. I've heard a couple of 5.0 owners swear by the platinums, one of them being the guy at the local speed shop - who probably has a hotter than stock ignition. Now it makes sense.

I have an MSD Coil on my Stang, but it still only likes the basics! Even if those Expensive plugs helped you a bit, it would be so slim that it would never offset the cost difference.

Thank you, I just put one on my car, and was beginning to wonder... It might be a different story with the MSD box?

If you're running a stock ignition, go with the standard copper plugs. Motorcraft, Autolite, Champion, or whoever, and like I said before, I don't know of anything bad to say about the Splitfire SF2Es - other than the price.

I have a naturally aspirated car with a carb on it and I went with NGK platiniums. I used the NGK because they were recommended by a long time Ford racer and engine builder. I went with the platinium because with the equal length shorty headers I have on it is a hassle to change the plugs. I do have a lot of mods and I am running a MSD box.

Why 24s, instead of 25s? That's one "step" colder than stock. What's the reason for suggesting a step colder?
