I ordered 4 Autolite Iridium's from RA for my s-i-l's 2015 CX-5 because it has 172K and she wasn't sure if they were ever changed. After ordering them I started reading on Mazda forums that only OE plugs should be used yada...yada...yada. Well, I changed them yesterday and I'm writing this to let 'Skyactive' owners know that it seems to be running great with the Autolites. I'll update if this changes.
PS: I usually use OE plugs but I have had good luck with Autolite Iridium's in every vehicle I've put them in. Also, the plugs I replaced were OE Mazda plugs but my inlaw thinks she may have had a dealer service it once....but she's not sure...the gap on the old plugs was over spec. by a bit (.050 vs. .043 spec'd).
