I couldn't get my sparkplugs loose on my 2.3 ecoboost mustang. I ended breaking porcelain off the sparkplug. is it possible i could have stripped the threading for the spark plug hole? I didn't get the sparkplug loose, so I just left it for the mechanic tomorrow, hopefully everything will be okay, and I didn't strip the threading. I doubt I did, but I noticed how easy aluminum heads like to strip if you aren't gentle enough.
