If you think OVT is not good enough, I’ll use true Mazda expert who designed the SkyActiv-G engine! Here’s what the Mazda CX-5 Factory Workshop Manual says:OVT? The guys that gave up on tuning this motor? You need another expert.
So, at worst, it's an extra $160 every 75,000 miles compared to the non-turbo version since the normally aspirated engine schedule calls for changes at that frequency.
Ed, I believe @jal142 means an extra set of plugs over and above the set the N/A engine schedule calls for anyway in the same mileage span. 1+1 turbo vs 1 N/A every 75K.It is an extra $160 every 40,000 miles and a trip to the dealer for the turbo version. Ed

I don't know who 'troyrig' so I can't impune his comments, but when someone tells me " I switched to premium fuel at 100k miles - 25hp boost and slightly better mileage." I have to question any other claimsJust found a more recent comment from the guy who had 145k. He posted about a month ago. Username is "troyrig". Here's his comment:
"I have a 2016 GT - Currently it's 4 years, 3 months and 190k miles. I just now replaced struts and shocks, sway bar links and first set of spark plugs. Otherwise it's just been oil, brake pads and tires. I switched to premium fuel at 100k miles - 25hp boost and slightly better mileage.

By "premium fuel" I assume he means higher octane. The 2.5T gets an extra 23 hp by using 93, compared to the 87 he was probably using before. He isn't wrong (with regard to the bolded statement). We do have to take everything else with a grain of salt though, as he has not validated his claims in any way.
I also question since that quote said he has a 2016 GT, which would be the naturally aspirated engine, correct? I don't think that engine sees the same power bump that the turbo does.
a spark plug change can be done in about 30 min for just the cost of the plugs and a spark plug socketI fully understand your comment ROCKETHEAD26. However, that extra service, regardless of the cost requires the average driver to visit the dealer. Most daily drivers don't like to visit dealers. I like my CX5 and my CX7 and do most of my own oil changes and tune-ups but, the added spark plug service, which is 2.5 times the competition is disturbing. Ed
Anyone contemplating keeping a car long enough to worry about an "extra" set of spark plugs at 80,000 miles would be well advised to learn to at least do some simple DIY like screwing in spark plugs or changing an air filter.a spark plug change can be done in about 30 min for just the cost of the plugs and a spark plug socket
NGK says NOT to use anti-seize in a TSB.
NGK has it on their siteThat's good to know. Apparently the guy on YouTube who changed the plugs on his CX 9 didn't know as he used anti-seize on the plug threads.
Do you have a link to the TSB ? I have downloaded a bunch of TSB's and shop manual info for my CX 5 but don't have anything about the spark plugs except for the Mazda part numbers and maintenance schedule where it shows to change them on the 2.5T every 40,000 miles.
Thanks
