Iridium was first used for long lasting plug tips, but it's rare.

Ruthenium is not as rare and when they discovered how to make
long lasting plugs tips with it, it's now an option.

really not much difference. both barely erode via electrical discharge,
so either/or but Ruthenium plugs can last longer

Can anyone confirm the part numbers for the non-hybrid engine? I thought I read somewhere that it was different to the hybrid version?

It would be nice to get a solid part number that can be verified for the non-hybrid engine. Thanks in advance if anyone knows.
