AntennaX The Shorty (5-inch) Antenna for Subaru Impreza fits 2007 thru 2014 Subaru Impreza Replace your factory antenna with this stylish yet functional LOW PROFILE (5 inch) black powdercoated billet aluminum antenna PLUG-N-PLAY installation, which means it screws onto your existing antenna mount (a direct bolt-on part, no wiring involved) and takes a minute to do 4 out of 5 reception with most people noticing no difference at all. As a general rule, strong stations will be fine and weak stations will be reduced Does not affect On-Star, Bluetooth, GPS Navigation, or Sirius XM radio as those Satellite services use a separate antenna in your vehicle
