This placement is more common in larger SUVs, European luxury cars, and some older models. You might need to lift the hood, remove a weatherstripping seal, and pop off a few plastic clips to lift the cowl and reveal the filter housing.
This is the least common location, but it does happen. If your filter is behind the dashboard, it is usually located deep in the passenger-side footwell or near the center console.
