Engine Air Filters when do you change them ?
When Toyota dealer inspected my Prius Prime before the 3 warranty ran out, one observation was the change the cabin air filter. Nothing regarding the engine Air filter.
So I went ahead and did replace both, but since there is no defined service interval other than inspect and replace if required. What exactly are we looking for ?
Here is the used Denso OEM air filter beside the replacement WIX part.
Not sure if the Denso started its life with the same color as the WIX
So for those of your that work in garages, when do you tell a customer a filter has be changed and when is blowing compressed air to clean it not enough ?
