Spark Plug confusion

[EllieCD55]

I'm new to working on my car and just got a 2021 Kia Seltos EX. I'm thinking about changing the spark plugs myself for the first time, but I'm a bit lost. I saw a few different plug types online. How do I know which one is right for my engine? Also, is there anything I should watch out for when removing the old plugs? I don't want to mess anything up

Appreciate any tips or advice! Thanks!

Hey i’ve swapped spark plugs on my Seltos before, definitely go with the OEM iridium ones from the manual. Just make sure the engine’s cool, and dont force the old plugs out. Take it slow when putting the new ones in so you dont mess up the threads

Clean around the hole to prevent debris from entering the cylinder.
As previously stated, don't force them if they seem stuck. They might be seized and require some release agent like PB Blaster or something. Use a spark Plug socket also.
Gap the new plugs and apply a bit of anti-seize evenly to the threads before installing them.
