Protects Engine Components. JLT's Version 3.0 Air/Oil Separator eliminates sludge buildup in the intake and the engine that accumulates on internal engine components causing premature wear. The JLT Oil Separator is ideal for Mustang GT owners that like to keep their engine clean for improved performance and longevity.

Version 3.0. JLT improved on the designed of their old Oil Separator with the introduction of their new and improved Version 3.0. The first big change you will notice is that the Version 3.0 Separator has a larger 3 oz capacity, that is almost double that of their previous model. Another important difference is the filter media. Older JLT Separators used a Ford Motorcraft pre-filter, but now JLT uses a 1/2" thick 1/16th" aluminum honeycomb filter with a mesh stainless steel screen to trap even more fine oil vapors than before to prevent them from gumming up your engine.

Superior Quality. This JLT Performance Air/Oil Separator is proudly manufactured right here in the USA. JLT CNC-machines their Air/Oil Separator from a solid block of billet aluminum for superior strength. Designed with a rubber o-ring, this Separator will maintain a tight leak-free seal. The base features a knurled texture, so that it can easily be gripped for removal during routine oil changes. JLT then completes their Catch Can in a durable black anodized finish for aggressive good looks and long lasting corrosion resistance.

Easy Installation. JLT Performance engineered their Separator to be installed in under 10 minutes with just basic hand tools. This kit comes complete and includes two PCV lines with stock-style quick-disconnect fittings that allow for an easy plug-and-play installation. All the necessary parts are included, with no cutting or extra modifications required.

Application. This JLT Performance Version 3.0 Black Passenger Side Air/Oil Separator is designed for use on 2005-2010 GT and Bullitt models. Installs on the passenger side.

Technical Note. This JLT Air/Oil Separator is not CARB certified, therefore it is not legal for use in California or other states adopting California emission standards. It is intended for off-road use only.

Do you offer an oil separator that works with Roush M90 supercharger?


  • Many of the oil separators that we offer will fit, as some have a universal fitment. With new hose or fitting, the JLT V3.0 Oil Separator, Item 394324/394325, will fit as the only difference would be the inlet nipple to the intake. The Mishimoto Oil Catch Can, Item 80227/80263 along with the Moroso Universal Aluminum Breather Tank, Item 14413, are universal and can fit almost any application as long as sufficient space is available for the tank. https://www.americanmuscle.com/jlt-oil-separator-v3-black-ps-0510.html https://www.americanmuscle.com/jlt-oil-separator-v3-satin-ps-0510.html https://www.americanmuscle.com/mishimoto-catch-can.html https://www.americanmuscle.com/mishimoto-catch-can-black.html https://www.americanmuscle.com/moroso-breather-tank.html

I have a JLT oil separator on the driver's side. Will adding this oil separator on the passenger side provide me with any additional material benefit?


  • Adding a separator to the passenger side will further help prevent sludge and blowby. Adding this also will give your engine a longer life as it still has the same functions as the one on the drivers side.

Which side is it more important to add the separator on? The drivers side or passager side? Or should you do both sides? I have more carbon coming out of the passager side tail pipe. Should I start with the passager side?


  • The JLT V3.0 Black Oil Separator will work best on the passenger side, however if you want to trap all blowby gasses, using both sides is more ideal.

    Works with Paxton

    If you don't use the provided hose it works very well with a paxton setup. The fit and finish was great and installed in under 30 minutes!

    Simple and easy to install. Black unit hides very nicely. Need to put some mileage on it now to see how it collects the oil.
