As long as you get an HRC Kit for a 2006+ TRX450ER it will work on your 2013 TRX450ER. FYI the 2006 to 2014 TRX450ER is the Identical quad exception of the Plastic's and Head Light Change in 2007. Other why's all the Engine/Carburetor parts in the 2006 to 2014 will interchange.
2005 TRX450R Ported & Polished Head, Decked Head at 0.30, 41mm FCR Swap (2007 CRF450R Carburetor), NCVQ Needle, Uni Filter, Big Gun Exhaust, HRC Cam, 11:5.1 High Compression Piston, & 15T Front Spocket.
