sorry if this has been answered in recent vent plug threads I looked but couldn't find, also it's probably a dumb question also but hey,

i have carbon art speed boards and mistral slaloms all but one board out of 5 have the goretex vents and with some mixed opinions on them paranoia has set in and I'm sure my 112 is feeling heavy, looking at the vents they are hex shape so do these come out or not? And simply replace with a new one?
