Today I checked the air filter on our 2017 Sport. I have never seen such a dirty/black sooted filter after only 7.5k mi. and 19 months since bought new. I was very surprised. (We don't drive on dirt roads and live not in a big city.) I highly suggest you check yours @ 10K mi. +/-. It's really easy to change out the filter and after you do it the first time you'll have no problems in the future. I put in a new Wix Gold 200215. ( White pleats on the Wix as compared to the factory yellow median which may be oiled?) Just a heads up.
