The direct-injected EcoBoost motor in the 2017+ F-150 Raptor is powerful and efficient. But direct-injection can lead to
oil vapors coating the intake manifold. This leads to a decrease in power and fuel efficiency. Oil separators, or oil
catch cans, filter out oil residue to keep the intake manifold, and the air entering your cylinders, clean.
Oil catch cans connect to the PCV system. A series of filters and baffles capture oil vapors and particles from the air
before it goes back to the intake. Oil separators will keep your intake manifold clean as long as you empty them
Installing an oil catch can is simple, and the relatively low cost makes them a smart add-on. They'll save you money in
the long run by preventing harmful build-up in your engine’s intake.
