2009 Impala cabin air plenum filter

Gen 8 Impala SS Cabin Air Filter
Plenum Water Intrusion Filter
AC Delco # CF174 or GM # 25958653
The Cabin Filter is removed for service.
A charcoal loaded filter is a chew deterrent for small furry critters. I laid a piece of #8 galvanized hardware cloth to the bottom of the cabin filter opening to keep the critters out too. The filter holds it in place and the edges are covered in cloth binding tape to avoid scrubbing off the paint.
Note the accesibility of the heater fan for sucking out any treasures a mouse or squirrel might’ve placed there for safekeeping… No need to remove the fan.
