Z31 AIV Plugs
thingiverse
The AIV is the Air Induction Valve that sits behind the driver's side headlight on the Z31. These two plugs are to plug the holes left behind on the intake boot, and to plug the line coming off of the AIV (the hose that comes off of the side of the AIV). Recommend printing in PETG due to heat/gas/oil resistance. A proper delete of the AIV would involve removing the pipe that runs along the frame rail underneath the car and plugging the downpipe. This plug allows you to skip that step if you don't want to do it.
