Why on earth do fiat advise changing spark plugs every year when other manufacturers say they last 60k miles or more?
Modern engines have near perfect air fuel ratio at all times so they should last. I bet they look like new when removed after twelve months.
My theory is that fiat have aways said that and have not updated their advice in decades.
I think I will give my plugs and annual check and only replace every few years.
