Buschur's oil separator catch can for the 2.0 Ecoboost will keep your intake tract and intercooler free from oil. The factory system draws crank case vapors that are contaminated with oil directly into the intake tract of your engine. This oil is then sucked into the turbo and passes through all the intercooler plumbing and intercooler. It has a negative effect on octane, gums up the combustion chambers and the number one largest side effect is it will absolutely DESTROY the efficiency of your intercooler. We have literally dumped a 1/2 quart of oil out of intercoolers!
This oil separator is a closed system, non-vented and SHOULD NOT cause any issues with any type of emission testing or inspections.
