AntennaX The Shark (3-inch) Functional Antenna for Acura MDX fits 2001 thru 2004 Acura MDX BRAND NEW IN PACKAGE!! Replace your factory antenna with this stylish yet functional LOW PROFILE (3 inch) Shark Fin antenna that will not hit the GARAGE DOOR anymore!!! Made out of Black ABS. If you are unsure that it fits, try unscrewing the existing antenna mast off. If it twists right off, then this antenna WILL FIT since it COMES WITH VEHICLE SPECIFIC ADAPTERS (no two antennas are the same fit). How to put it on--Installation is very simple. This is a PLUG-N-PLAY antenna, which means it screws onto your existing antenna mount (a direct bolt-on part, no wiring involved) and takes a minute to do. And the way your car looks after this Shark Antenna is installed is incredible! How is the Reception--4 out of 5 reception with most people noticing no difference at all. Is it worth it--This compact high quality Black ABS Shark Fin antenna cleans up the appearance of the REAR of your car and is an extremely durable upgrade from any stock antenna. A great improvement for little money and effort!
