PCV Valve confusion

[BFlat]

Will be taking some parts off for replacement & figured it will be a good time to replace the PCV valve and grommet since it would be easier to get at. Did searches and found several suggestions at all different costs, all of which got at least a few negative reviews. What PVC valve and grommet should I get for a stock GN that will never (he says now) see over 15 lbs of boost? Thanks
