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.
What kind of annoys (and surprises) me more is the time element. A lot of Porsches, including mine, are low mileage vehicles, so we hit the time well before the mileage. Does a 10K mile Porsche really need new plugs after four years???
For the record, I didn’t replace them in my GT4 until a bit after the seven year mark and 10K miles… Never had any issues, and the last time I was at the track, power delivery still felt great, but I took the car in for another service, and the tech recommended I replace the plugs, so I did. Don’t judge me.
