2018-2023 Ford Mustang Air Oil Separators

Every air oil separator here fits 2015-2023 Ford Mustang GT 5.0L, EcoBoost 2.3L, and select GT350/GT500 models. Fitment splits by Coyote generation -- Gen 2 (2015-2017) and Gen 3 (2018+) -- with kits from Ford Performance, J&L 3.0 billet, and Mishimoto baffled separators.

Do I need a catch can on a 2.3L EcoBoost? Yes -- direct injection means fuel never washes the intake valves, so an AOS traps oil vapor before it bakes into carbon buildup. Closed-loop kits keep your PCV sealed and 50-state legal.

Verified Coyote and EcoBoost fitment, no guesswork.
