GR Yaris Plugs

@Duke

Did you get the ruthenium LKAR8BHX (91784) again? Just ordered a trio. After reading through the thread, I’m going to treat them as a 20k mile service interval item. I read that they are factory gapped at 0.8mm, will probably put them in as-is.
No, I don't think they lasted any longer than the standard plugs.

I just bought another set but haven't fitted them yet due to an undesirable Yaris/fauna interface scenario taking my car off the road for five weeks and counting :(
