      Air oil seperator

      Bada** canisters and they work instantly, I did have to purchase my own 3/4” male fittings for the hoses

      Catch can

      Does the job but abit too big, breather is too high, might need to trim the hood to make it fit.

      Nice product

      The welds are really good it’s a quality piece but will do the same as an eBay separator. Only reason I got it is because I have moroso reservoirs. But still overall I like the product

      Moroso Universal Aluminum Breather Tank

      I installed this right before going TT. Very easy to use and does the job well while still looking clean. I run e-85 now with my twin setup. I never knew how much blow by these coyote engines had until I saw the gasses escaping from the top of the breather. its a relief knowing that these gasses and oil are not being sucked back into my intake. great product!

      Awesome product

      I put this on my procharged 99 svt cobra and it's great, bolted it right to the firewall and routed hoses from each pvc valve right into the catch can, no more oil all over my engine bay under high boost

      The best.

      Well, so far, so good. This can looks to be a quality product. I like knowing that the sizes of all three ports are big enough for V8"s. I don't know if I could call it "baffled", but there is a tube that goes about halfway down, then there's a stainless pot scrubber in there. Hey, it works. Also, it looked to be too big for my 2011 GT's engine compartment, but it turned out to be exactly the right size. Perfect fit.

    I'm a Noob! What is this!? Hi, sorry to bother. What is this? I want it and have read that it doesn't allow oil into the engine but was wondering what this is exactly. I drive a high performance V6 3.8L would I benefit from this product? Thank you!

    • Hi Kbails84...These are generally used on engines with a super charger and they will keep the super chargers from drawing up oil which can get into your intake pheleum and make a gooie mess of it. I'm running a kenny bell super charger on my stang and I have 2 of these oil air filters on my engine. They do an exellent job of catching the excess oil that would other wise be sucked in to the intake passages. I don't think you would benifit from them unless your running a super charger on your car. I hope this helps you out!

    I have a 2006 V6, how in the world do I install this. I have it drilled in but I have no clue where the hoses go

    • To install the Moroso Universal Aluminum Breather Tank you would need two ended male nipples with a 3/8" fitting on the other side and some hose that connects to the nipples from the catch can on one end. The two other ends of the hose will be routed to the PCV with one hose and one to the intake, on the other hose. If you attach the other to the intake tube and not the intake manifold, just remember to attach it after the MAF, as oil vapor will damage it. You will need some miscellaneous adapters and clamps depending how you install it specifically.

    Will this fit V6 Mustang? Will this breather tube sit up fit and work well with a 2004 V6 Mustang?

    • Yes, this Moroso Breather Tank has a universal fitment and will work perfectly fine on your '04 V6.

    Does this come with fittings for the side of the tank where you would hook your hoses to?

    • This will contain the tank, the filter, the drain plug, and the mounting bracket.

    I am prepping my 97 Cobra for a KB 2.1 and I know for a fact that my top end is prone to sludge (see it first hand). I have a JLT oil separator now but it is closed, would I benefit from both an open and closed system using this product in conjunction with the JLT or is this overkill? 1 answer

    My car is turboed and my intake tube does not have an input for the other hose to connect to. Can I run a hose from the PCV to the breather tank and then just plug the other end so it acts as a remote breather tank? Also if this is possible can I do the same thing for both valve covers and have two breathers? 1 answer

    hi, i was wondering if this would be a decent addition to a high mileage car? i have a 06 V6 mustang with over 200,000 miles. it has the basic upgrades (which do not include forced induction) but because of the mileage of my car i was wondering if this would be a good idea to install for longevity sake (minimizing sludge). if not, is there another product or catch can that would be better suited for my needs? thanks. 1 answer

    Im completely confused. from reading the other questions. They answered that this part is mainly for engines with a supercharger to prevent extra oil from getting sucked into the supercharger.
