A used Audi Antenna Booster, OEM part number 8D9035225B, is a genuine factory component removed from a donor vehicle. This booster amplifies radio signals to improve reception; a failing unit often causes weak or intermittent audio. Also known simply as an antenna booster, it comes from select B5-generation Audi A4, A4 Quattro, and S4 models equipped with 1.8L turbo, 2.7L twin-turbo, or 2.8L naturally aspirated engines.
