Holy cowabunga, Mazda plugs are $$$

2023 CX5 turbo
Have over 32,000 miles so decided to look up ordering some sparkplugs for the 40,000 recommended plug change and dealer msrp is over $35 per plug...at least it looks like a simple job. looks like Mazda Swag has them for $25 a pop but $14 shipping. I guess ordering an air filter at the same time will lessen the pain :).

for me I can always come up with lots of reasons to get a new vehicle as I have a sickness for new cars but $100 or even $140 once every 2 1/2 years or so for spark plugs isn't one of them. What is your list of negatives that you have compiled? So far at a bit over 32000 on my not quite 2 year old cx5 I have not found too many things that have me willing to fight with the wife about to trade it. She loves it. My only real complaint is the info system. it is probably the least friendly info system I have come up against. there are several things I don't like about the info system and strangely enough the lack of a touch screen isn't one of them.

Seems like all the car makers are trying to make ways to extract money from their customers after the sale. Like 'activating' seat heaters and other stuff.
 
Buy any of the suggested plugs that Rock Auto lists for your car.

I went upgrade with NGK Ruthenium HX 92274, which have fine wire ground and center electrodes, which I believe promote a faster growing flame kernel.
 
All Mazda oem parts are made by someone else. Buy aftermarket and don't worry about it. Most products are made by a few companies. Kelly Springfield tires are made by Good Year. I never worry about name brand products only the cheap imitations.

These NGK plugs from Rock Auto are supposedly the same as the Mazda ones (without the Mazda logo). I changed them at 40k with the NGK's on my 2021 Turbo.

I broke one of the OEM plugs and replaced it with a Rock Auto NGK on my turbo. It runs like it's hair is on fire.

I have a set of these on the shelf when the time comes...

@AL Cx5 -- Just checking ...

That link is for the NGK #90288 Laser Iridium, gapped at 0.030". Does your turbo CX-5 take plugs gapped at 0.030"?

Asking, because my own 2016.5 CX-5 owners manual specs plugs gapped at 0.044".

In another year I'll be doing the plugs on my CX-5. Did the NGK #94124 Laser Iridium last time (gap 0.044"). Open to the 0.030" gapped NGK #90288 if they provide a noticeable improvement in performance, smoothness, fuel economy. Strongly considering the NGK #92274 Ruthenium HX, for its claimed improved performance and fuel economy.

Dunno why you're changing plugs at 40k miles. The maintenance schedule for my 2016.5 calls for 75k miles. Even the severe schedule 2 states the same 75k miles.
 
I was chasing after a misfire thanks to the NGK spark plugs I bought off Amazon. After wasting a good amount of time and money trying to figure out what it was, some new Bosch plugs fixed the issue completely.

Interesting, can you explain this video to me then? What other car lasts this long with so little problems or repairs? Other than Toyota, hardly anything else out there.

 
The turbos, at least the newer ones (mine is a 2021) call for 40k changes on the plugs. It cost me about $65 with tax and shipping from Rockauto and about a half-hour of my time. I've heard of dealers charging over $400 for a spark plug change on the turbos (using Mazda branded plugs).

mazda recommends 40,000 miles in a Turbo and people that have done that say the plugs definitely need it.

I believe that is what mazda plugs are pre-gapped to

my brother in-law in Rochester Mn said the dealer wanted to charge him $400 for changing plugs and he declined. He is not mechanical and he put it off and then had some warranty work needed and he said the dealership initially gave push back on the warranty work but then went ahead and did the warranty work. The plugs were totally unrelated to what he needed warranty on (the transmission).

unfortunately there are even counterfeit spark plugs on amazon and ebay.

That's what I think the issue was. Or maybe dropped during shipping. I think it caused some micro cracks on the electrode or insulator which expanded enough to cause the misfire, because it only occured after a few months of regular use, and only after warmed up. Plugs looked fine to the naked eye. Never again.

Changing them is a pain though. Bending down to reach the engine of my Mazda 6 at 6'3 is a nightmare 😂

I used 0.030" gap for Turbos.

That's an interesting plug, HX, NGK is a solid company.

Please report back if you use them.
