Reduces Engine Sludge. Stop the formation of sludge in your Mustangs high powered engine by installing a JLT Version 3.0 Air/Oil Separator, more commonly know as a catch can. A JLT Catch Can will prevent crankcase blow-by, an oily exhaust vapor, from re-circulated back through your PCV system and intake. If left unchecked this oily vapor can congeal into a gummy mess know as engine sludge. Over time this nasty sludge will coat the inside of your throttle body and intake manifold robbing you of power and performance. A JLT Separator is ideal for use on all Mustangs whether they are a daily driver or a dedicated race car.

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 Driver Side Air/Oil Separator is designed for use on 2005-2010 GT and Bullitt models. Installs on the driver side, same side as the PCV valve. Will 

NOT fit with supercharger with the exception of Saleen supercharger. Will 

NOT fit FRPP manifold or vehicles with aftermarket fuel rails.

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.

I noticed that there are specific ones for each side of the vehicle. will I need to purchase both?


  • You will only need one JLT V3.0 Black Oil Separator to make it work, however, to capture the most amount of oil from entering the intake, we would recommend the passenger side, item 394324, in additional to the driver-side.

I have a Turbo set-up on a 2005 Mustang GT and the hose that this connects to on the intake manifold is currently plugged. Can I still use this? Or will it mess with the Turbo/Tune?


  • The JLT V3.0 Black Oil Separator will technically still work as long as both of the ends are plugged in correctly. The only issue with plugging the separator direct to the manifold on a supercharger or turbo charger kit is that it is be subject to positive pressure. If the positive pressure from the supercharger or the turbocharger exceeds to pressure from the PCV, the PCV would not open and/or could become damaged. If you plan to use a catch can or separator, we would recommend using a unit that will allow you to connect the line post-maf but before any part of the system that is susceptible to positive pressure.


Helpful (0)

Do you have to empty out that catch can ever so often, and if so how often?


  • The JLT V3.0 Oil Separator has a smaller catch can so we would highly recommend checking it at least every 1000 miles. The interval period will vary as every vehicle is a little different and you may collect more/less compared to another Mustang of the same year. We recommend checking it every so often and emptying the separator on an interval period that correlates with its oil consumption/collection.

I have a 2008 GT. The car has a black ram-air 1960's style air intake kit sticking out of the hood that the Ford dealer had put on the car by a car customizer. The car was brand new. Being that this kit is a permanent thing, will this separator fit on it?


Does this fit/work with the California Pony Car fuel rail covers?


Will this fit a 2014 gt?


  • This air-oil-separator will not work with a 2014 GT. The 2011 and newer Mustangs use two angled fittings, were 2005-2010 models used a straight fitting and an angled fitting. We have an air-oil separator designed specifically for your application, however, it is the passenger side and not the driver side.

    This product is exactly as advertised. Takes like 30 seconds to hook it up and it does it's job well. I checked the can 2 days after install and already had some oil collecting in the bottom! This thing is perfect preventative maintenance for those with low miles on their car and want to take care of it for the long run. Highly recommend.

    A must have.

    I bought this because i had heard things about them but never owned one myself. i put it on my 07 gt that had 60,000 miles. By 70,000 i had already gotten almost 7 ounces out of it. I will never drive another sports car without a catch can on it.

    Great product

    Dont waste your time buying cheap knockoffs. The JLT oil separator looks like it came on the car from the factory. Installs quickly and easily, and is a quality product that you can trust to keep the oil out of your intake unlike the knockoff brands that will do absolutely nothing. Spend the extra money and protect your motor. I give it 4 out of 5 stars only because the hoses are slightly longer than they should be which puts a slight bend in the lines. Very minor so in no way will it effect airflow, but something to expect.
