18-Up Wrangler JT/Gladiator 3.6 Liter Crankcase Vent System Kit TeraFlex

The TeraFlex Crankcase Vent System Kit is designed for compatible Jeep JL and JT models equipped with the 3.6L engine. The system helps prevent engine oil from entering the intake during steep vehicle angles and demanding off-road situations by adding improved crankcase ventilation and a secondary PCV arrangement. A ball-check valve helps control fluid movement during extreme operating conditions. The system integrates with the engine while maintaining convenient service access and helps reduce the possibility of oil ingestion, hydrolock, and related engine problems.
