Field feedback said, use an impact on the plugs while the engine is hot. Fewer failures have resulted in this method.
I'd think same would apply to Two Valve Plugs, probably any of them.
I might do that on the Corolla, another Aluminum Head, but I can get at them and snatch all four while the motor's hot.
As somebody noted, a V10 isn't gonna stay hot for the time it takes to gain access and then remove 10 coils and remove 10 plugs!
That said, V10 in an F-Series, maybe four hours will work. I doubt an E-Series will be that quick.
