My '09 Corolla comes with iridium plugs OEM with a specific long reach specification. Each plug is located under a its own coil pack. All of this under an engine cover. The more one messes around un-attaching & re-attaching coil packs, moving & flexing plug wires etc. the more chances of failure. These components have to deal with heat and vibration so I don't need add excess flexing/handling to the mix. My Corolla's plugs are rated for 120,000 miles or 192,000 kms.

I have always used OEM specification for may cars. I have never had a plug failure or even a code showing misfire in any car I have owned.
