Very cool. Thanks.
I think I found the thread you are talking about
So with my supercharged GT it looks like I should just go with stock/factory spec plugs and stick with Motorcraft coils and plug boots, yes?
Anybody know a good source for those parts? I'm seeing prices of around $275 for a set of coils and boots. Maybe I don't need to replace them all, but 1 has been sitting in coolant, another the conductor spring is all rusty, those two have been misfiring, and third has a broken connector on it. The car has 62,000 miles on it. I'm right to be wanting to just get a full set of new coils, boots and plugs, right?
