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.
I personally believe it’s because Porsche thinks they every car they sell will be tracked every weekend so they make recommendations for service based on that idea.
