So my co-worker just helped me replace the Cabin Air Filter in my 2018 Rogue for the first time. Rogue has about 21000 miles on it. I guess I probably should have replaced it earlier, it was pretty nasty and when we pulled it out a whole bunch of leaves and crud came out. Last time I was at the dealership for an oil change they wanted $120 to change it. Ended up getting this one on Amazon for $15 - https://www.amazon.com/gp/product/B07GY ... UTF8&psc=1
They definitely don't make it easy to get to that filter to change it, you basically need to contort your whole body. Also the filter we got is a lot stiffer then the OEM one so was slightly difficult to get in.
