Fuel Injection service
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.
Thank you all for your valued help !
