2012-2016 oem antenna base (39152-T0A-A11) & antenna (39151-SWA-305) will fit and plug in just fine... I did the opposite for my wife's 2015 crv, she liked the look of the sharkfin. So we swapped the 2015 antenna for the 2018 sharkfin. As far as reception I can't say whether it made a difference or not, she doesn't travel out of town.
