These are hard to beat, and last at least 50k on that car.
Putting a mileage life on an air filter doesn't mean much. How long an air filter can last is almost solely dependent on the local environment, where the vehicle is driven (I suspect highway driving is 'cleaner' than city driving), if the vehicle is parked outside or inside, and so on.
Does it really matter if the car is parked indoors or outdoors as long as the engine is not taking in any air?
Sorry, the outside parking scenario I was thinking of is related to where
it may be parked, i.e. under a tree, for example. Personal example is a parking spot I used to use at work that was under a tree (I liked it for the shade) that had small, teardrop-shaped leaves that fell off all spring/summer/fall. On many days, my car could have a hundred (??) of those on it including many in the cowl (?) area which leads to the air filter inlet. When I've changed the cabin air filter, there were many leaves caught by the filter.
