      Superior Performance. This V3.0 Black Driver Side Oil Separator will guarantee that your new Mustang will perform at its finest. JLT designed this oil separator with an optimum filtering capacity that traps fine oil vapors and releases them once heavy enough to fall. Subsequently, they pass through an aluminum honeycomb filter where they accumulate and fall to the bottom. Moreover, its new and improved 3.0 version includes a higher oil tank capacity of 3 ounces for improved engine life. It also has a knurled tank base for easier access to remove and drain the used up oil. An O-ring secures a leak-free surface seal. On top of that, JLT embellished this oil separator with its CNC laser-cut logo for quality brand recognition with a notable sleek styling.

      Sturdy Construction. JLT engineered this Driver Side Oil Separator using solid billet aluminum for superior strength. This material is designed to provide maximum protection from high temperatures. Furthermore, its black anodized coating prevents corrosion and maintains the excellent appearance in extreme conditions.

      Easy Installation. This Driver Side Black Oil Separator is designed for an easy, hassle-free installation. You just need to simply mount the JLT bracket with the oil separator to the shock tower tab, and install the plug-and-play OEM hoses into the GT’s valve and intake manifold. The installation process completes in less than an hour using basic hand tools.

      Limited Warranty. JLT warranties the original purchaser a 1-year limited warranty from the purchase date for this V3.0 Black Driver Side Oil Separator, against factory defects in workmanship and material.

      Not CARB Certified. This JLT V3.0 Black Oil Separator is not CARB certified at this time. It is not legal for use in California or other states adopting California emission standards. It is also not legal for use on pollution controlled motor vehicles.

      Application. This JLT V3.0 Black Driver Side Oil Separator is specifically designed to fit 2018-2020 Mustang GT models.

        2019 GT with Roush Supercharger

        These work with the Roush supercharger installed also. The driver side fits out of the box. The passenger side needs the short hose to the supercharger from the new T installed removed and then with the end cut off the separator hose will fit on the T.

        Not an oil separator

        This is not a separator, will try to return. This does nothing. Goes between air filter and crank case. Only clean air goes through it.had to give it one star but it should have a -5

        2018 Mustang GT

        It was easy to install, but I had removed my sound tube before installing. This made it easier to fitting the location.

        Great product, works great!

        I gave it a 5 star as it works great but the mounting location is a tight fit with the factory air box!

        Is it needed on the driver's side...

        High quality piece. I installed this on my Mustang at around 800 miles ish. Installation was a little more involved than the passenger side. I took my time and actually took the 10mm nut off and removed the sound tube rather than ripping it out like I've seen seen in some videos. It's really not that difficult to remove especially if you have a 10mm ratcheting wrench with an adjustable head. Installation is still simple, just takes a little longer depending on your method of removal of the sound tube. I just had my first service completed at a little over 5,100 miles. When I got home I checked the capacity and it was BONE DRY, literally like I had just taken it out of the box it came in. My car is 100 bone stock, at this time, in case anyone was wondering. I didn't figure much would be in it but I didn't expect it to be absolutely dry. Of course I will leave it on since I already have it. Maybe with modifications or more miles some oil may eventually appear in it. I'm leary on recommending it, I mean if there isn't any oil in it, there's simply no need for it on the driver's side. That's the only reason for 4 stars.

        Oil seperator install

        I recently installed this oil separator on my 2018 Mustang GT Premium 5.0L. I installed the passenger side separator previously. The fittings to the air intake and the valve cover were spot on. I removed the sound tube and used that mounting location to mount the bracket and oil separator. It works nicely. The only fault I had was the length of the hoses on both the air intake side and the valve cover side were way too long. Especially on the valve cover side. Probably 3-4 inches too long on the intake end and about 6 inches too long on the valve cover end. The intake end was not the problem though. It was trying to find the space to route all of the hose on the valve cover end. One way was too low and I was afraid that it would get too hot. One way it was resting on a coil pack; didn't like that idea so much. I finally found a way to kind of "nest" it up under the strut tower brace near where it attaches to the strut tower. That particular piece of hose needs to be more of a straight shot from the oil separator to the valve cover connection. You can make some angle adjustments where the hoses attach to the can. That proved very helpful; especially on the valve cover end. The whole unit is very well made and I'm positive that it will function as intended. It just has some fitment issues which need to be addressed. Overall I'm not sorry I bought it. Would do it again. Just required more creative routing than I had anticipated. Passenger side was a piece of cake.

      Hello I am wanting to install the Oil Separator on my 2018 Roush Jackhammer with the supercharged Coyote. Anything?

      If I were to have the passenger side separator, is there a need for a second, driver-side one? What would it do for me?
