Doing the necro thing here but any 5/16 check valve should work here for 2016s. Process is pretty easy after getting a solution for the MAP intake. On a 2016 you need a check valve going toward the Intake and connected at the T point of the Evap line. After that you can plug the secondary line that goes to the cold side charge pipe.
Buy a PCV from Boomba, Damond or whoever in 5/16 inch (8mm), and pick up some 5/16 Gates wiper/vacuum hose from OReilly auto parts, some 1/4-3/4 worm clamps from Home Depot, a Dorman vacuum plug kit and pull the stock cold charge pipe vacuum line. It connects to the stock intake and the charge pipe and it's a quick connect. Use a Dorman vacuum plug and worm clamp on the post of the cold side pipe. Then install your intake. Cut the old line off at the T fitting, connect and clamp the hose to the T, shortly after that clamp on your check valve close to the T with air flowing toward the intake, and connect the other end of the hose like you normally would to this system.
I'm still interested in getting this intake, just waiting to see how the sound deadening efforts have panned out with the foam and baffles.
