Makes sense....Anyone aware of the earlier breather ports not having these VGs and there after getting fitted on.
As NDWDCPGUY said, the original breather was a flush louver on the cowl panel. The SB
introduced the extended breather mast to keep the oil streaking on the fan cowl to a minimum. The small vanes on this new mast have been there since day one.
