Yep, They're Spark Plugs
So for the extra $3 to go from copper to iridium it was a no brainer. I really don't notice any difference in performance, however the benefit of iridium is that I don't have to change these plugs for years to come. That is worth more than $3 a plug because they are a bugger to change on a FZ07 thanks to the tight space and tough to remove coil packs. I did it without removing the tank, so I could have made the job easier on my hands had I done it that way.
