Default 5.0 Spark Plugs





I recently Installed Spark Plugs on my 5.0 - And the guy at the Advanced Auto Parts said "Gap them to 54" ?
Well i did, The outcome is the idle feels worst lol. And then someone told me to gap them in between 42 - 46 ?
What is the proper gap for this car!!!

And Can i salvage the current Spark Plugs , If not i will rebuy i went with Motor Craft the first time should i do it again!

I messed around with different gaps and found that a .040 gap worked the best for me (Autolite 24s.) I went as high as .054 and as low as .035.

Edited to add: of course, this is only because it's not NA

*edit* I was making a generalized remark. Not all of the people working at part stores are as useless as you think... hell. I bet I could find a few that would make you look like a noob.

I gapped mine to .050. Seems to run fine so far. What is the voltage on a stock coil?

autolite 25s FTW. In these 5.0s a standard resistor autolite is pretty much the best plug you can run IMO, and i'm sure lots of people on this forum will back me up.
