SkyActiv spark plug options?

[MANICompression]

Has anyone changed their spark plugs yet and gone with an aftermarket plug? If so, how has your experience been vs. the OEM Mazda plugs that came with the car? I'm considering a set of Denso Iridium TT's or Champions compatible with the 2.0 Sky-G. Thanks in advance.

Thanks, although I across that thread before, still looks like the jury's out on whether or not OEM plugs are the only option for the 2.0 Sky-G. I'm wondering if anyone who has gone the aftermarket route is experiencing normal engine behavior and mileage. Looking for anyone who has to chime in on their experience so far.
