spark plug help
ok Im gonna be changing out my plugs (and also thinking of trying for that Bosch contest thing) and need to kknow is it one spark plug per cylinder or two? I assume I need two for a set or should i need all 8 for 1 set?
there wording is a bit confuseing as they want to know how many i need to be one set (i assume 8 total right?) thanks for the help!
also as a side note i did reference my haynes manual and couldnt find the answer i seek.

Tear your truck apart? You can see the plugs just looking under the hood 
Yes when I bought my truck it has Bosch 4 prong plugs. Changed the plugs to motorcraft ASAP.
If you search on here everyone will recommend running Motorcraft coppers.

ok, whats bad about the bosch ones? ive used them in other vehicles with pretty good results i dont see how our trucks would be too tearibly different from say a Nissan (which had bosch plugs in it). my truck has its motor crafts still in it so i haven't tested them vs the newest bosch ones (plus i think it might be fun to get some statistical data to spread around here to help others out 
) but please enlighten me

Been there done that. They suck and are a waste of money. Ive had Bosch, NGK, Motorcraft, and Autolite. Motorcrafts were my favorite.
You can search. There are a ton of threads about spark plugs on here.
Ford and Nissan not much different?

Honestly, Everyone has their opinions.
The first set of Motorcraft plugs I ran in my expy wasn't good. Ran them 50K miles, and they were done with.
Bought a set of Bosch Iridium's ran them for at least 90K, and still had more time left on them.
I entered the Bosch Contest they had on here, and I was the lucky winner! Don't know if they had more than just me as a winner, but anyways. I just installed them.. (Same ones I bought last time) and I'm happy with them. I also run the same plugs in my 99 Firebird. Couldn't complain one bit.
From here on out, I will stick with Bosch Iridium.
(btw, does anyone know where I post my review for the contest?, I have looked and looked, and can't seem to find it. They didn't post a link for the thread in my email, or PM.)

It has to do with the ignition system and maybe the engine design to some extent.
All my fords have had cheapo copper core plugs and they have loved them, bought them with ngk, bosch etc installed and most of the time noticed a difference changing to the copper cores. Had an old t-bird with duraspark ignotion that i put bosch somethings in years ago when i didnt know better, ran poorly, then tried ngk which may have been worse before going to std cooper plugs and it smoothened it right out.
Just put a set in to my 89 f250 which i got with new ngk's installed, smoothed out a light throttle miss i had. The ngk's looked fine and even colour when i removed them but the engine just didnt like them.
Call me crazy but they just work better. I do know from other experience that the jap engines like ngk plugs over all though.
