Scotty I own a 2019 Honda CR V LX ( bought the LX in order to get the 2.4 liter engine sans turbo). I have 15,500 miles on the car and do my own oil changes, brakes, and light maintenance. I have a local guy like you for anything serious, or tires etc.as I'm 75 now and slowing down a bit. My concern is the engine air filter when I inspected it for the first time I noticed a black oil or tar like substance on the lower side of the filter, I thought perhaps it was something that got sucked up from road work and changed the filter. This last oil change I again inspected the filter and found the same crud in the bottom side . This air intake has a different construction from our 09, and 15 CR V's in that it has a vertical enclosure / duct in front of the air box, so it's hard to tell if anything is going on there. Any thoughts, should I be concerned ?

Thanks
