When your 2015-2018 Mustang GT vents crankcase pressure, small amounts of oil vapor can enter your intake system, coating your 5.0L V8's inlet tubing, throttle body, and even blower rotors on supercharged Mustangs. The oil coating can cause pretty serious performance losses that can easily be prevented with an oil separator. Our selection of high-quality Mustang oil separators come with a small tank to store any excess oil and only need to be emptied when you change your 'Stang's engine oil. When you're finished here, check out our selection of Engine Dress-Up accessories to add a stylish sheen to your engine bay.
