Humming noise
I have a 2015 with 164000 miles, I had same issue but was coming from my tires. Found out I needed new front shocks and alignment, that was the causing it. Being in Arizona I have to also lube the drive shafts due to the heat and dryness, not sure if you have the same issue.
I noticed that filter myself, as I was replacing the old one. I was thinking about removing it, but still undecided if it matter or not on HP or MPG. I’ll do more searching to see what is the outcome with or without.
