Question type: Maintenance & Repair

My car is a 2017 Mazda CX9 with about 24000 miles I was told I should get a
fuel injection service plus a cabin filter is this needed

The cabin filter is a good idea. I doubt you need the FI service. This must be your stealership's suggestion? Use a bottle of Techron in your gas instead.

I would recommend replacing the cabin filter yourself. Search You tube for the location on your car. Usually behind the glove box. Takes 5 minutes and the dealer will charge you $50 or more to change it. I would also skip the Fi service.

Cabin filter yes, Injection service is a no. Techron is good stuff unless your already running Chevron or Texaco fuel then you don't need to add any as the fuel already has it.
