its pretty simple basic electrical theory, you will change the flow (resistance) of electricity with different conductive materials. the ignition coils store and spike voltage specifically for iridium spark, think of it as a magnet, a magnet sticks worse and better with different metals

Yeah I actually have coppers in my car but will go back after reading up more about them. The older platinums are straight up worse than copper but last longer. The iridiums provide better performance at lower amperage and last longer and are more resistant to melting.

In saying this all the race engines use copper in the 1nz-fe but they do not care about longevity of stock parts or fuel efficiency.

I read this below and it enlightened me some

I think I will get NGK BKR6EIX-11 online, the are one step colder but still listed for 1nz-fe. I like to rev it and want to track it one day so this is a good choice for the "spirited driver" who does not live in a very cold location.

Interesting to know all of this. Of course with hundreds of thousands of miles on the car you really arent concerned with longevity

Picked up a set of NGK BKR6EIX-11 from market place of course! $60 nzd for the set guy wanted $80 lol im terrible...but why pay full price when if you check marketplace someone is probably selling some cheap they don't need? had been listed 6 weeks..easy haggle! hahaa
