Spark Plug replacement 2015 QX70

[urhstry]

Been following a few posts about changing out spark plugs and have read that you have to change the coils with them, however others have not and I am wondering how you can tell if the coils are ok since they are expensive to replace. Any decent aftermarket?

If you aren't having any misfire issues, then I would not change the coils. That seems to be a huge waste.

Agree. Just swap the plug unless you have misfire or you see cracks on the coil pack.

How many miles are people finding the original spark plugs last? Mine is a 2015 with 60k miles ... I know it says change at 105,000 but that seems like a long time. Should I change them now? No engine issues, just wondering.
