most people on here use the Bosch super 4's or the NGK Platinum, I have ran NGK Platinum in other Turbo cars and they have been solid.
I only went for the Denso Iridium because they were on offer and I got them for the same price as a set of super 4's but they were a range colder.
Unless they are on offer again, I wont be getting them lol and probably go back to the NGK or Bosch
