Looks like they make one, just the listing only shows up to 2011.

That is correct, the 2011 has the N55 engine. Not sure how long Injen has been producing them, but they sell for just under $400. I like that the Injen removes the entire stock airbox. Just looks cleaner. I know the BMS one is very popular, but I thought I read a study where the results showed it was actually pulling hotter air than stock. Also +1 on FREON's comment regarding the BMS Cowls. And the N55 does not have a BOV it has a diverter valve.
