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.
