Epoxy. JB weld (non-metallic) works great.
Seriously...tossing out a coil because it has a crack in the case is really wasteful, IMO. Slap some epoxy on that crack and get another decade or two out of it. I’ve done it plenty on other cars and never had a misfire return.
The best part is that you can be up and running today instead of waiting for parts.

To each, their own, though.
