So You Just Have To Have Iridium Spark Plugs eh? - Toyota Yaris Forums

They aren't identical plugs though, and I see both plugs on the right are worn out? This isn't exactly an objective test. That being said, I also believe that running strictly iridium plugs is kind of silly. A spark plug is a spark plug. If it works, it works.

They are worn alright but the owner reported his engine was running fine and he didnt think he needed to change the plugs.

Maybe he didnt. Maybe with electronic ignition they would work forever.
