Should I use or return these spark plugs?

I got some spark plugs from the dealer today. I've never changed plugs before so I don't know if this is a big deal or not. I'm hoping you could share your expertise:

Out of the 6, this one was noticeably the worst:

You can see the left is higher than the right side


Same plug, the close side is bent to the left:



Same plug, here you can see the bottom is bent to the left:



Plug 2, here the left side of the top and bottom are slightly closer together:



Please vote and explain!

 

Nobody knows about this?

 

return and get regular ngk or denso

FWIW ... I would return them and get the "stock OEM" plugs.

I run nothing but NGK in ANY of my vehicles.
