ok the shop says my 3rd cylinder spark plug blew out and i mite need a new head and intake. what u guys think. how much do u think they are going to charge me
Yep that helicoil fixed me right up. I think mine blew out as hard as it could stripped the threads on the head and tore the boot all up.I don't think you'll need a new head, and 99.99999% sure you won't need an intake. The only way I'd see it would be if it shot that spark out with a tremendous force which is possible, but not likely at all.
They should try to helicoil the head so you can toss that spark back in.
However, it is possible that the stock intake is cracked, which was an annoying issue with the 96-98 GT's. I am pretty sure that was taken care of when the switch was made to the PI intakes from 99 and on.
Mine blew out at wot in 4th 6k and around 127mph. It took out the threads and the boot. The spark plug was a little embedded in the intake where it tried to squeak by.Usually the only damage is the coil that breaks at the mount bolt
