The noise is horrifying the first time you take these plugs out. That was the part I hated the most.
Haha, yeah, the noise is definitely unnerving. I had one that I swear was making crunching noises when I first started turning it out but it all came out intact.
The driver's side rearmost one screeched and scraped and made all kinds of godawful noises but also came out intact.
PB Blaster and/or some kind of carb cleaner or seafoam is your friend on this job. I mostly used PB Blaster and it immediately dissolves any carbon buildup that it touches.
