I like that the cabin air filter has charcoal in it to which help absorb oder which adds functionality. The feel of this filter feels like a fabric is used which adds quality to it over the thin water ones out there in the market. The install was easy and fit right inside the filter location with ease. Even though this filter is a higher quality filter of OEM, it does not restrict any airflow whatsoever.
