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.

    high compression turbo engines reduce spark plug life.

    Also, shorter service intervals make dealers happier.

    Fiat 500 engines (1.4 MultiAir, at least the turbo one) has 30,000mi intervals. Also, the valvetrain system uses electrohydraulically-actuated intake valves (created from oil pressure). To protect this complicated valvetrain system, a mini oil filter (MultiAir filter) needs to be changed along with the spark plugs every 30,000mi. Neglect of these two parts is a huge reason why these engines prematurely fail, in addition to typical Fiat build quality issues.

    My GT3 interval was 10k kms. Seemed ludicrous but I imagine things need to be pretty exact at 9k rpm.
