    Ordered Mazda plugs which just arrived.

    How many times per vehicle life do you change the plugs? 1-2 times 99% of the time. I figured it ain't a place to save 50 bucks.

    Curious if they will look the same as the ones I got when you get them.

    They might look the same.

    I've read here that apparently Mazda's plugs can provide resistance(?) readings while ngk do not. (or something of this nature?)

    That was a wrong guess. Based on post #47 from Anchorman, two recommended OEM spark plugs listed in our owner's manual both are resister type. PE5R-08-110 is NGK ILKAR7L11; PE5S-08-110 is DENSO ZC20HPR11. OEM plugs do have MAZDA mark and its part # printed on the ceramic insulator.

    Denso Iridiums in the V8 of my GX. Service interval is 12 years or 120K (~193k km) miles in that vehicles owner's guide.

    It's gonna be a number of years before I will be replacing plugs in my CX-5 but will go OEM when I do.

    Purely for info, that is the Mazda parts website.

    Mazda site also told me there was 3m tape in 4 specific locations under my spoiler and how to remove it. There was none. Mazda dealer even confirmed it was in their supply chain. Again, nada, when I removed the spoiler. Stuff is fickle.

    Just got a set of new plugs from the Mazda dealer. This is on the box. Same numbers (both) are printed on the insulator of each plug. Sure looks to me that NGK provides OEM plugs for Mazda.
