Those look thin wall to me, most chrome sockets are, you might compare them to the Icon and see if the icon are any thinner.
You should be able to look the plug number up and find the hex size:

I do have a set of thin-walled spark plug sockets from Performance Tool that I got from Amazon. Comparing the pictures with the Harbor Freight ones you linked to they do look the same.
About the 14mm spark plug socket size, I have seen the newer plugs are going to this size and the older is the 5/8" size socket. Just don't forget you'll need an extension to get the spark plug socket down into that spark plug tube. I've found that some of the newer cars, the plug is much further down there than in the past.
What I also test is to see if the rubber insulator that holds the spark plug into the socket will come out when you pull the plug out, I've had to dab a little rubber cement in some because the last thing I want to do is trying to fish out that rubber nub stuck to the plug after I've installed the plug..
here's a link to the performance tool brand spark plug set, compare the pictures to the harbor freight ones, they do look like the same wall thickness.

Thanks! I was reading 12-15 ft lbs on random sites.
If you have time, spend $10 on Amazon for this magnetic socket. It will make spark plug changes a cinch to perform on the Corolla.

I received counterfeit spark plugs from Amazon.com. They lasted about 20k miles and started throwing misfire CEL. Upon inspection, the electrodes were worn away and almost non existent.
I have the exact same tool for my Toyotas. Worked great on my old Corolla.
20 nm is 14.8 ft lbs
Getting the plugs from the dealer will ensure you have the correct ones and minimize the possibility of getting fake ones.
Sorry, I can't advise on what kind of socket you need. My MB GLA45 takes a 14mm socket for the spark plugs and I just recently replaced them. The only 14mm spark plug socket I could find, and buy locally quickly, was a 12 point but the plugs were 6 sided. I didn't feel comfortable using the 12 point to break them free and for final torque so I ended up using my 6 point deep socket to loosen and for final torquing and just using the magnetic spark plug socket for removal and install.
If not already planned for, after you remove the coil pack/extension, I would recommend looking down the hole at the plug and surrounding area and blow some air in there to remove any loose dirt before you remove the plug. Maybe even rig a small tube (piece of fuel hose or similar) to a vacuum hose, long enough to reach all the way down the hole to get any other loose dirt after removing the plug and before installing the new plugs.

Excellent recommendation of making sure nothing is in the spark plug tube! Your post reminded me of what I do, I usually use a long straw and a can of compressed air (without tilting the can and getting refrigerant out instead of air). That definitely is a must just to make sure nothing is down there.. It usually isn't because the coil pack seals up the tube well but it doesn't hurt to make sure!
and yes I was amazed how many 12 pt spark plug sockets are out there.. no thanks! It's either 6 pt or forget it. Sounds like you got it done well with what you had at the time!
Yes, you matching with the random sites gave me a bit more hope. I've done plugs by the "and an extra half turn" method before, and that "feel" seems about that level of torque. So I wasn't super worried overall about torque. But thank you! Now I can set the wrench and wait for a click rather than pray...
30 minutes today. Saved $300. Went with Denso Iridium Long Life. That's what came out from the factory.
Thanks for the update.. and nice to save $300 for something that wasn't that complicated..
when you removed the plugs did they make that crack and then eek-eek sound as they came out? I know you were concerned about them being easy to remove after being in there that long.
I wish all cars were easy like this for changing out spark plugs. My old 2001 F150, not so much...
A little pop at first and then a feeling that was kinda crunchy as I turned them out. But not awful. Pretty simple. I'd say they were tightened about 15ft lbs to release. I tightened to about 15ft lbs with torque wrench.
Wife's Subaru will probably go to the dealer. I saved money here, so the $500+ will be worth it, including new PCV
ahh.. makes sense, glad it worked out well! So how's it running now with the new plugs? Notice any difference? After I recently replaced the plugs on my friends (new to them) 16 Mazda CX-5, it was running more quiet and the fuel economy then jumped up about 2-3 mpgs. They had been in there for 70k miles (factory install) and Mazda recommends replacing them at 75k (it was either 70k or 75k miles).
When warm seems subtly smoother when idling. I'd also say when accelerating up a steeper hill it seems to "hunt for power" less. It used to kind of stutter at a light that was moderately uphill when I'd take off from a stop. Seems less noticeable now. Could also be my imagination because it's not significant. These had 110k on them from factory. As far as MPG's, no noticeable difference. I don't think plugs make more than decimals different unless they're WAY past needing to be replaced. All the computers adjust to maximize efficiency so well nowadays. Still pulling about 38mpg with some city on weekends and mostly freeway during the week.
Not completely identical, but I find the Denso Iridium Twin Tips does give a little extra power compared to the stock Long Life plus. I use Twin Tips in a 2007 Matrix.
