There's a reason GM went bankrupt.

Yes, the Chevy Monza! Although the engine is not transverse mounted, when equipped with an optional Buick V6, it would have problem to get to the last 2 spark plugs, and require the engine lift-up too.
Also during 1980’s, GM also came out the “innovational” 8-6-4 V8 with cylinder deactivation and it’s a total disaster! It proved that the cylinder deactivation simply doesn’t work!

Well, it proved that it didn't work with the technology that was available at the time.
Well, my 2015 Acura MDX also has cylinder deactivation (called VCM for Variable Cylinder Management), many had problem with it but mine works so flawlessly, I really can't tell when it's activated. Some brilliant engineer figured out how to disable the VCM in Acuras with aftermarket gizmo, so should with Mazdas, I thought.

I've heard horror stories about the VCM failing and causing massive oil starvation issues. This was mainly in the first gen of that system though. By 2015, they probably figured out all of the bugs.
I went with the NGK OEM replacements at about 77k miles and couldn't tell any difference. But Mazda uses the plugs to measure ionization in the cylinder predicting pressure and that can predict spark knock and cylinder pressure at various crank angles. Since these engines emulate Atkinson Cycle, knowing the pressure is valuable. How much info Mazda uses is known only to Mazda, but clean plugs should give better info. Mine were certainly clean enough to have run to 100k miles in most other engines.
I think most want to forget the 1980's "feedback carburetors"

I was more interested in ensuring they were OEM than fakes and from years of experience with company I know that is all that they sell.

EDIT: I should have checked.. this was previously recommended by yrwei52
Plugs came today... might change this weekend but not sure yet.
This 14mm thin wall socket I used on my '07 G35x holds these plugs nicely.

I have a 12 Pilot with basically the same V6 with VCM they've used since 2009 and through '22 models. VCM eventually cokes oil and compression rings of the shutoff cylinders, causes excessive oil consumption and plug fouling later in service life, hammers on the engine mounts, and of course many (especially with AWD) experience a variety of vibration and shudder, especially in cold weather.
Honda doesn't enable VCM operation until coolant temp reaches 167F. The Honda VCM disabler device simply keeps the REPORTED coolant temp to the PCM below 167F. If the actual coolant temp exceeds 220F or something like that, the disabler device reports the actual temp so overheating can be detected properly. My'12 runs flawlessly with the disabler.
I don't think Mazda uses the same strategy for VCM and thus can't be disabled as elegantly. And Mazda uses continuously variable intake/exhaust cam timing, which Honda does not.
Extremely easy spark plug swap. Changed oil/filter and spark plugs yesterday. Old plugs gap was still within spec and passed the ohm test as well.

How many miles do you have on your 2015 CX-5 right now? And do your new OEM spark plugs look exactly the same as factory installed plugs?
Just a quick glance they looked exactly the same. I'm just shy of 68k miles. So an early swap but it will probably be another 8 or so years before replaced again as it appears I am only doing about 8-9k miles a years.
