im thinking about changing out my spark plugs, all i have the the stock ford ones, which ones should i go with, the originals, bosh,spitfire... does any one of them make a difference with my setup

Split fire is good, or any other copper plug.

I go with the NGK iridium's they have been awsome in my stang, and it is very temperamental when it comes to plugs. They are a little pricey but worth the cash.

Just don't get platinums.
If you're naturally aspirated, I wouldn't drop all that green on iridiums.
Motorcraft coppers are probably best.

Motocraft coppers are good, I only use NGK iridium in my bikes and you notice a huge difference there. ($12 a plug)

autolite copper or motorcraft copper, don't get bosch our engines seem to hate them.

should i get a bigger coil with the ngk's? like a msd or.. what do you guys recomend?

Better coil is also a good idea, if you have motorcraft or NGKs.

There are as many different answers to that as there are brands of coils. I like Crane or MSD personally.

i've read on here that some people have had some problems with the high-end spark plugs. So just a forewarning, if you start having problems, go back to the cheap ones.
