This Moroso air/oil separator is specified for 2014–2018 GM trucks with 5.3L or 6.2L engines, offering crankcase ventilation management to reduce oil carryover. It mounts in the PCV/vent lines to trap oil and return it to the sump while allowing clean air to vent. The unit helps keep intake and PCV systems cleaner on modern GM V8 applications when added as an aftermarket service item.
