What is the socket size of the spark plug?

You will use either a 16mm deep socket or 5/16" spark plug socket for installation. Be certain to verify each spark plug gap at .044" before you install.

2012 Hyundai Elantra—Amazon says it fits this car but has anyone tried it?

According to the NGK Part Finder, it only works for the L4 1.8L Engine. You need the ZFR5FIX-11 for the 2.0 Engine. The OE Part for the 2.0 is IZFR5L11

Are these better than the original honda crv (2011) spark plugs (denso sxu22hcr11s)?

I think so. I have iridium plugs in all my cars.

Easy to install

Easy to install. I watched a couple of YouTube videos before installing. Took my time and was happy I did it myself. It would have cost me $200 of more to have the dealer install these. Seems to run fine, will have to see if gas milage improves.
