Spark Plugs!

So I'm sorry to post again but I am really bad at finding things online apparently... I have reached 30k on my 2016 Passion and I am looking to do the maintenance myself. That being said I am having trouble finding the spark plugs I need to get. So I am looking for some help!

My engine is this: 1.0L L3 DOHC 12V

Thanks in advance :)

Are spark plugs a 30K service item? I don't have a gas Smart, so I don't know. Just curious since most plugs go a lot longer now.

There are different duty cycles for iridium plugs. one style has a duty cycle of 30-45k miles, the other has a duty cycle of about 100k miles. The center electrode is larger on the longer duty ones. The smaller electrode ones say they are a performance plug and will give a hotter spark for better economy and easier starting among other claims. I would rather change plugs every 100K miles than more often at 45K. But I do a lot of driving...
