the Gearwrench magnetic spark plug socket with attached extension.
The USA Kobalt Spark Plug sockets Cripe has are from the Danaher era (Armstrong, Craftsman, KD, NAPA, Allen, etc). That said, I have all of the 3/8" sizes they offer (branded Kobalt and Allen) and they're great for being the classic rubber insert USA spark plug sockets. No complaints for any of them.Another option is cripedistributing.com and buy USA made Kobalts (aka Williams) for cheap.

Matco has a 6 pc set that is an expanded version SPK6 $115.95:

Truck brand inflation is crazy. That set use to be less than $100 not that long ago.

If you have a good socket or set already, snap on will sell you their inserts (a-la-carte) for under $5/ea bucks shipped.
You could re-do a whole set of 16/18/20.6 for under $20. Something to keep in mind if you are on a budget and the actual sockets you have are decent/work fine for you.
All that aside, I'm a big fan of getting a specific fitment for your application.
