i've cleaned out countless intake manifolds with clogged ports etc from crank case venting so i know the issues and didn't want to mess with it on a new vehicle (2019 ZR2). after reading a lot of reviews it seemed to me that the ProVent filter is probably the best option for this vehicle, but normally i would have tried to put together the hoses and brackets myself. unfortunately, due to a recent move, i don't have a workshop and although it's pricy, the kit saved a lot of time and was first class all the way (not affiliated). this is just my instal write up for anyone interested
