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.
Might be for emission standards. In the seventies I worked on Alfa Romeos we had to Use Lodge spark Plugs at about $15.00 each ( champions were about a $1.50 ) customers complained but we had to use lodge in order to make the cars emission legal.
