Quick Help Please RE; Spark Plugs

[Invader_X]

Now there are two listings for the rear and front banks for GPX - Iridiums at the back and copper at front

I can see this as a cost perspective why they did things like this from factory

Or does this have somehting to do with how engineers designed the car?

Will I run into long term problems running Iridium's all throughout?

Thanks all

Run all Iridiums. Was done purely because the back bank is more difficult to change.

Sweet as, thanks Bennoz.
