Is this not an issue on 2009's or 2010's? I've only heard of this issue on 4.6's and 5.4's in trucks. I was under the impression the stangs had different heads. Or maybe I misunderstood and it's the 09's and up that have different heads.
Wish I would have seen this this past weekend lol..my buddy and I were changing the plugs in his 06 and the plug broke off. he had to have it towed to the dealer and they charged him $100 to get it out.. (luckily, the plugs were under recall from Ford so he gets reimbursed for it all) but good info will definitely remember this if it happens again.
So you were SCd with stock plugs? I've got a PH turbo on the way and Mike's going to be sending me HT0's with the kit. I got 4 off last night and will attempt the other 4 tonight.
Luckily all 8 of mine came out with 40k on the clock. passenger side was pretty clean but driver side was starting to get a decent amount of carbon. How did you all clean the seat where the spark plug sits down in the head?? There was a lot of trash down in there.
