For pretty much their entire line including the 4 cylinders, V6 Turbos, and flat sixes, they require a 30k/4yr (40k for a few) interval while most other manufacturers are doing anywhere between double to 100k mile intervals. I believe when they share the same engine with Audi (2019+ Macan S) they do shorter plug intervals. I don’t think it’s a money making scheme since they recommend 10k mile oil changes which ironically I prefer doing at 5k.
Just bitching because I’m not looking forward to doing the plugs on my car soon. Have to remove an upper engine mount, air boxes, and reservoirs to get to the plugs in the back.
The FI vehicle requires good spark delivery to keep from knocking as well as on higher psi vehicles there’s the ability to blown out spark causing knock. Also esp on flat layout motors they serve as a slight heat sink helping pull heat out of the combustion chamber. Heat that also can cause knock. Just change the plugs dude.
