Replaced the engine air filter on a 17 Forester a few times in the last few years due to fall fires and smoke. Every time I check it it's plastered with grass and debris. Looks like the air intake might be near the grill. Didn't look too closely. The resonator box below the filter has grass in it, too. I clean it once a year and pull handfuls of grass out. And tap the filter out. And pull grass from the filter box. This car is almost 100% on road, freeway miles. I've never had a car that collects grass and debris in the filter box area better than a lawnmower. Anyone else notice this with Subarus of this year/filter setup?
