For sale: Engine Ventilation System (CVS Kit) from the original TeraFlex company, which is the best and most suitable alternative to the catch can for Jeep Wrangler JK 3.6L engines. Its primary function is to prevent engine oil from entering the intake manifold during ascents and descents from steep inclines or when stuck at sharp angles. Key Features: - Engine Protection: Prevents burnt oil smoke from exiting the exhaust and protects the engine from hydro-lock or internal damage due to oil ingestion. - Working Mechanism: Adds a second PCV valve at the front of the engine via the oil cap to ensure only air is drawn, not oil, regardless of the vehicle's tilt. - Preserve Original Parts: Installs while keeping the original factory oil cap and without any impact on the emissions system. - Easy Installation: Smart design that installs directly without complexity. Compatibility: - Jeep Wrangler JK / JKU (2-door and 4-door) with the 3.6L Pentastar engine only (2012 - 2018 models). Note: - Does not fit 3.8L engines, nor the new generation JL or Gladiator. Condition: - New in its box
