time to change spark plug?

2 Attachment(s)

Can someone tell me if I need to change my spark plug out?
I think it have about 70,000 miles on it.
A shop changed them out for me when I went from S/C to stock.
They installed Denso K22PR-U for me. I thought my 2006 tc use Iridium IK20?

I got 4 Denso Iridium IK20 for $25.
Here are the comparison to Denso K22PR-U that was in my car.
