I'd say, for everyday driving go for the Iridiums. Since a few forumers have mentioned that the cost all adds up excluding labour fees, you risk less with issues, ie. installing/removing them. Get originals and basically they would be worry-free throughout their lifespan.

V12Kompressor funny that most P2 servicing outlets state 100,000 KM as their lifespan for Iridium Power. Sources say the lifespan is indeed 50,000 KM, so why did P2 overrate them?
