most people say around 60k...

i pulled mine out at 60k and they looked pretty good, but i dont regret changing them.. now i dont have to worry about it... but i would say the 60k mark is a good time to change them...

and most people just go with the stock motorcraft replacements... they are a good plug...

so really just stock motorcraft plugs are good, I was just not sure with autolite or NGK, I just want the best plug for performance and driveabilty, because both autolite and NGK have differnt grade levels of plugs like, ex.G-Power,V-Power etc...

Bosch Platinum 2's here. No need for gapping.

Haha, that's funny because on my old 98 GT, I had to yank the plugs and wires at about 85k because the car would cut out at full throttle up high in the R's. Do I really need new coil packs, or will plugs and wired suit me fine?

Ok folks spark plugs don't give you better MPGs. If you gained MPGs after changing plugs that means the plugs that were in there were fouled and making your engine run less than par in the MPG department.
