I definitely would if you are going through with venting to atmosphere. My 2012 was vented to atmosphere by the previous owner but the media was still in the ccv filter, I would see pressures getting up to 5 psi in the crankcase under high load, he’ll even medium load I could see 2.5-3 psi at a time. Just doesn’t relieve the pumping pressures fast enough if the media is left in. Couldn’t imagine what pressures could be seen if you were to have weak piston ring sealing. 5 psi might not seem like much but it is extra stress added to oil seals pushing outwards from inside the engine. My take on it anyways.
