Ford Performance oil and air separator, right for Mustang GT 2018-2020

Mounting on the right side (in front of the passenger) of the engine compartment. At high outputs, the oil is pressurized and oil vapors are generated in the engine compartment. As a result, the oil can enter the fuel mixture, thereby reducing the octane number of the gasoline, and the oil settles on the spark plugs and reduces their efficiency. For more efficient combustion, smoother operation and cleanliness of the engine, it is advisable to install an oil-air separator, which traps pressurized oil and oil vapors generated at high speeds and prevents them from mixing into the injected mixture and settling on the spark plugs. The system is not universal, designed for Coyote engines.
