    OP, run from your current stealership, and take it as a warning sign to stay away from all of them if at all possible...

    Arrow Spark plug change interval confusion

    Spark plug manufactures usually don't recommend gap adjustment on iridium plugs.

    Specification

    Spark plug type
    PE01-18110, PE02-18110

    Perhaps they're different from those in early models and 2016 has a different plug.
    Furthermore,

    Spark plug gap (PE01-18-110, PE02-18- 110)
    Standard: 0.751.10 mm {0.0300.043 in}
    New spark plug (reference): 0.750.85 mm {0.0300.033 in}

    Spark plug gap (PE5R-18-110, PE5S-18- 110)
    Standard: 1.051.40 mm {0.04140.0551 in}
    New spark plug (reference): 1.051.15 mm {0.04140.0452 in}
    I have never experienced any difference in ignition by installing a good NGK/Denso spark plug instead of OEM one. I've always used iridium or double iridium.

    Does anyone know of any other make/model that requires iridium plugs be replaced as soon as 40k? Seems way low.

    Agreed.
    Really? Preventative maintenance is considered a waste of money? Do you notice a change when changing the oil, air filter, diff fluid, coolant, etc.? No of course not.

    If you do preventative maintenance and notice a performance difference, it means you went beyond the point that, that component or fluid was intended to last. Meaning you were running sub-optimally prior to the maintenance being completed.

    Yes, REALLY! He's saying he could've went to 100k easily, and I agree, however, I'll buy the NGKs and do it myself, so who knows when I'll change em, won't be before the 60k mile warranty is up, that is for sure... Don't get me started on preventative maintenance...You've got fools around here changing ATF at 15k miles, and every 15-30k thereafter...Comical. I'll run mine until I trade it in at 100k most likely, not a worry in sight...

    I have a car I change the spark plugs on at every oil change. Granted, it puts out almost 300hp p/liter to the wheels, and yes, you can damn sure tell when you don't... Cost me less than $8...lol

    Actually, every 3k (only car I do 3k mile oil changes on, if it makes it t0 3500-4k, who cares ). Cost $8, wtf not, plus, it's basically a given with the tune on the car...

    Granted, if I had a Skyactiv 2.5T, I'd roll with the 40k miles, but idk, I couldn't keep one stock, so I'm sure more frequent plug changes would be in order...lol

    Who here is changing their ATF at 15k miles? Methinks you over exaggerate.

    Nope ,sure didn't...

    I've seen 15k, 30k, and 43k on here, with every 15-30k thereafter... All comical as all get out...Hopefully you can blame it more on gullible fools and stealerships more than preventative maintenance concerns...lol

    Over maintenance =/= preventative maintenance
