Description
Help protect your Ford Mustang's engine from oil vapor buildup with the COBB Tuning Air Oil Separator (AOS), designed for compatible 2015–2023 Ford Mustang EcoBoost models. This engine protection upgrade is designed to separate oil mist from crankcase ventilation gases before they can circulate back into the intake system.
During engine operation, crankcase ventilation can carry oil vapor and other contaminants into the intake tract. An air oil separator helps capture and separate oil from these gases, directing the separated oil back toward the engine's oiling system while allowing the remaining gases to follow the intended ventilation path. This can help reduce oil residue in the intake system and support cleaner intake components over time.
Manufactured by COBB Tuning, the Air Oil Separator is a practical supporting modification for Mustang EcoBoost owners who want to improve crankcase ventilation management on a daily-driven or performance-oriented vehicle. It can complement other compatible engine and turbocharger upgrades.
Before purchasing, verify the exact part number, installation requirements, and compatibility with your Mustang's model year, engine configuration, and existing intake or ventilation components.
