I own few mustang in the past, mostly fox body and pre 98 gt , now im having around 7k to find me a nice 99+ mustang gt with 5 speed or auto is fine, dont plan on doing any mod, just driving and cruising , for the past few years while on this forum, I did saw spark plug blow out common problem on 4.6, this is what I scare about for the 99+ gt. Should I be affaird ? what should I look for when I buying a 99+ mustang gt, I know it very depenable, and the 4.6L is bullet proof, I own few in the past.

I didn't change mine till 140K. And that was only because the intake manifold was getting swapped. Car still ran great...I just figured while they were in there, why not?

Still ran the same after the plug change but the idle was a bit smoother.
