I have a 2015 Tacoma TRD Sport with a 4.0 V6 engine. It came with copper plugs that you're supposed to replace every 30K miles. I've already replaced them once with OEM copper plugs and am wondering if I could use iridium plugs for longer intervals? Why would they still use copper in the 6 cylinders and not in the 4 cylinders? Thanks!

I don't see why you couldn't.
The point is just to make sparks right?
