It was during the installation. I think I overtorqued it a little bit.

Should I just take it to a shop? They would probably extract it with an easy out and if that doesn't work pull the head (aka more or less a head gasket repair).

google "fake NGK" and you'll get lots of info
Yeah, I bought them from Amazon and they were gapped incorrectly. That should have been my first sign that these plugs were counterfeit. Lesson learned.

I got my money back and promptly picked up 4 genuine ones from Autozone for when this issue gets resolved.
