    Spark plug change interval confusion

    Hello all.

    I recently had my 2016 cx5 serviced by the dealership. While there I was recommended to have my spark plugs replaced. I had 60,000 miles on the odometer. I declined, because I believe I could do the job myself. As I was gathering all the items to do the service, I noticed in the owner’s manual that the plugs don’t need to be changed until 75,000.

    Today, I got a text from the service manager asking how my visit went and I shared my concern that they were asking me to change my spark plugs 15,000 miles too early. He responded with a phone call and explained that some cx5 have a 60,000 requirement, while others have a 75,000 service interval. The manager said the service writers are instructed to follow the 60,000 interval for everyone to make things easy.

    My question to you all is do any of you have a 60,000 spark plug service interval on your cx5 or is the dealer “BS”ing me.

    Thanks.

    That is BS. It is 75,000 for all of them.

    That dude had to come up with something. And quick. And I bet he was very honest and authority-beaming on the phone...

    Moral- they're in there not for you, but for themselves only. This will never change. They will upsell you on anything they can get away with. Good for you for trusting, but checking. Make sure you don't take anyone's word, always check and question.

    The Stealership is lying. All CX-5's (not sure about the newer ones with the turbo, so let's just say all NA engine CX-5s) have a 75k interval for spark plugs.

    They are clearly doing this to bring in more $$$ because even though you and I could buy the spark plugs for around $50, and take 15 minutes to do ourselves, they will charge $300ish give or take to do the same job. And if they are getting people in sooner than needed, that easy $$$ for a simple job.

    Changed mine around 80, or so? Ran the same. Same mpg. Plugs looked fine. plugs gapped within 0.001 of spec. Waste of money.

    Yes the maintenance schedule on spark plug replacement is much shorter on SkyActiv-G 2.5T. It's 40,000 miles instead of 75,000 miles.

    One reason the Mazda dealers charge a lot more for spark plug replacement is because OEM spark plug is almost doubled on list price comparing to similar NGK plugs.

    Still that's $100 for the plugs. The last dealer I went to prior to doing them myself wanted to charge something like $325 for the job. Highway robbery!

    Thanks everyone for replying. I thought it didn*t sound right, but I wasn*t sure.

    Speaking of spark plugs, I bought some NGK laser iridium plugs rather than mazda branded ones. NGK says on their website that these plugs are the actual ones used by mazda. Any one else have these? If so, how are they working for you? Did you recap them?

    Do you happen to know the correct gap and torque spec? I believe the correct torque is 12-14 pounds.

    I have the oem Mazda plugs, but they indeed carried the NGK model number, so I definitely will go NGK route next time.

    Unfortunately don't recall what the torque spec is, ill see if I can recall that somewhere.

    Really disappointed that MAZDA has a 40K spark plug replace that early. Many owners will get overcharged from less than honest dealers for this service. Ed

    That's for the Turbo. Everything else is 75k.

    And that's the price you have to pay by having more powerful 2.5T turbo. More maintenance, and more gas.

    I torqued until the crush washer went solid and then a touch. I think I probably did around 10-12 if I had to guess.
    I forget the correct gap. Its been about a year.
