The cabin air filter is located under the hood on the passenger side, in front of the exterior grill.
You do not need to remove wiper arms to install the filter.
Pull the rubber cowl weatherstripping outward. Remove the weatherstripping on the passenger side about halfway across toward the driver side.
Remove the cowl grilled cover, it has plastic fasteners that does not need tools to remove.
Start be pulling the end of the panel gently upward enough to pop the plastic fasteners up so you can remove them by hand. Be careful when pulling on the plastic fasteners as they could be very sharp on the edges.
There will be an old plastic air inlet cover under that cowl grilled cover.
You can either remove the plastic fasteners like above or you can cut the plastic rosebud fasteners.
Clean the area and you are ready to install the new filter.
