I think your 2013 is the same as my 2012. There are 4 total:
50830-SZA-A02 Front Engine Mount
50810-SZA-A02 Rear Engine Mount
50820-TK8-A61 Engine Side Mount
50850-SZA-A02 Transmission Mount
The part numbers may be updated for the 2013, but this could get you started if you want to search online for them cheaper. I got the front and rear mount (genuine Honda) online at ebay for half the price.
Search here or on the web for tips on how to check if they are bad. Youtube was also helpful to me when I was doing the research.
