Ngk iridiums silzkre7e9 at 56,387 miles

[oil pan 4]

OEM spark plugs for 2018 Hyundai sonata hybrid with the 2L Nu engine and 56k miles.

I'm thinking copper anti-seize, stick them back in, run'em and check'em again around 90k miles.
If the iridium is still in tact next time I check them between 90k and 100k then blast them with baking soda and stick em back in.
These appear to be double iridium or at least iridium center with platinum landing pad for the spark to land on the arm.

Throw some new ones in there and be set for another 8 years. Less work, less to think about.

Hard to say one way or another on the plug from the picture….

The in focus wrench however, is GOOD TO GO!

Mine don't come out nearly that blurry at 60k. It's a good thing you changed them.

Since you went to the trouble of removing them just put a new set in and go to 100,000 miles. Gives you peace of mind.
