Iridium vs platinum spark plugs

I recommend using the same brand and model plug that came with the car. Don’t try to get more miles out of it. The longer a plug stays in that engine the greater chance of having it freeze in there and it can be a lot of work trying to get it out. Plugs, even platinum plugs are cheap in the long run.

Different brands may have a slightly different thread and buying a different brand may cause problems
