Working on changing the spark plugs on my 2002 V6 Highlander. Wondering if a cracked coil like in the photo below is cause for concern?

If it operated normally with that crack, I say you will be okay with continuing to operate it until you change it or have to change it. Just keep it in the back of your mind until you feel the need to change it. It's your choice.
