    Hey guys, this is the Mishimoto Direct Fit Baffled Oil Separator System with red hoses for the 2015 and newer GT. The Mishimoto Oil Separator System is a catch can setup that plugs into the PCV line and it's a great way to protect an engine. It's a simple mod that does some good for all applications. You don't need to have a forced induction setup to be able to utilize a catch can or even any major modifications. But I will say that once you start modding, it is an important piece of the puzzle. A catch can might not be one of the first mods that's on your list, or it may not even be on your list at all, but it's a very functional piece that has benefits to it and can do good for even a completely stock motor. The install here is easy, it's a one outta three wrenches in the difficulty meter. So we're gonna take it back to the process of an internal combustion engine for a second, so I can explain the benefits of an oil catch can like this one here. So the ignition of the air and fuel mixture inside of the combustion chamber is ignited and it forces the piston down. There's a small amount of that mixture that leaks past the piston rings and into the crankcase. This is known as blow-by, and in that blow-by, there's an oil mist. The blow-by and the oil mist will then settle in the intake and over time, they're going to form a gunky buildup. Now technically speaking, there can sometimes be condensation along with the oil mist and the blow-by, and if you let all of this hang out, the worst case, this stuff can make it into the oil inside of the crankcase. This is not a good thing and it's considered oil contamination and dilution. So you've got your PCV valve to help fight this issue. The PCV valve alone has its own list of weaknesses, and engines have regulations as far as emissions, so the current setup as far as crankcase ventilation system means that an engine will have detonation or knock when oil is in the combustion chamber. If the knock sensors pick this up, they're going to pull timing, and that's never a good thing. Another thing that happens is carbon buildup on the piston tops and the valves as well. Enter into the scene the oil separating catch can. It's gonna push these gasses, the blow-by and the oil mist and the condensation, through a baffle system that's gonna trap the oil and separate it from the other gasses. The gasses are gonna be allowed to continue through the intake so that they can be burnt off and the oil will stay in the catch can so it doesn't move on and cause issues for the engine. So this is a single catch can that will mount in line with the PCV system. Inside it has a 50-micron bronze filter that's going to separate the oil from the air and the other gasses. The can itself has a good amount of capacity and you'll notice that the better catch cans actually catch a lot of oil. So the larger capacity of this can means that you'll be servicing it less. And the bottom of this just unscrews when you wanna empty it. It's sealed with an O-ring, so it won't leak at all. This kit is gonna include everything that you'll need for the install. You have the mounting bracket so you can mount this. It's gonna sit right near the PCV valve and it's gonna be positioned so that it's in an easily accessible area so then when you do need to empty it, it isn't a fight. It's also gonna come with red silicon hoses that have some pre-installed, stock-style quick disconnect fittings which are gonna make the install so easy. It'll be completely plug 'n' play, it doesn't get any more straightforward than this. And the can itself is a billet aluminum can that's sealed like I mentioned earlier, and of course, powder-coated black. As far as price, you're looking at spending a touch below 200 bucks for this catch can from Mishimoto. And one thing I will say about the catch cans in general, is to be wary. You wanna make sure that you're getting a good one that'll trap as much oil as possible. Some catch cans are just an empty container with a few ports, but these kinds are not gonna condense the oil vapor and trap as much oil as possible. You wanna make sure that the catch can has an internal baffle and collection system like this one does. So the install here is really pretty easy. You're looking at spending an hour tops, and this is gonna be a one outta three wrenches in the difficulty meter. Just need some basic hand tools to get this all done, and I would start by assembling the can itself and getting the mounting bracket on and all of the fittings into place. The engine cover will need to be popped off so you can get to the PCV area right behind the throttle body. You're gonna end up swapping your stock PCV hoses for the Mishimoto ones, so you can remove your factory hoses. All of the hoses just snap in. The fittings install into the catch can and the can attaches to the bracket and installs on the car. Then it's just a matter of installing the hoses to the can and getting your cover back on. Mishimoto recommends emptying the can every 1,000 miles, so just make sure you check on it. Wrapping things up here, the Mishimoto Baffled Oil Catch Can is a direct fit for the S550 GT, and you can check it out more online right here at "

    Reduces Engine Sludge. It doesn't matter if your 5.0 Mustang is an all weather daily driver or a dedicated track car, blow-by is robbing you of precious power. Blow-by (crankcase exhaust) is an oily vapor that is re-circulated back into your engines intake through the PCV system to be re-burned. Unfortunately over time blow-by will actually coat the inside of your intake and throttle body with a sticky sludge that will restrict performance. However, you can fight back by installing a Mishimoto Air/Oil Separator (better known as a catch can) to stop this contaminated oil vapor from re-entering your intake preventing the build up of engine sludge in the first place.

    Internally Baffled Design. Mishimoto engineered their Air/Oil Separator with an internally baffled air diverter that increases the turbulence of the incoming air which in turn improves the separation of the oil from the air. The included 50 micron bronze filter further prevents smaller oil particles from re-entering the intake system.

    Superior Quality. CNC-machined from 6061 billet aluminum for superior strength, this Mishimoto Air/Oil Separator is designed with a rubber o-ring for a tight leak-free seal. Mishimoto then completes their Catch Cans in a durable black anodized finish for aggressive good looks and long lasting corrosion resistance. The base can easily be removed for draining during routine oil changes.

    Easy Straight Forward Installation. Mishimoto designed their Catch Can to be an easy straight forward install that can be completed in under 30 minutes using basic hand tools. The included PCV silicone hoses feature pre-attached stock-style quick-disconnect fittings making Mishimoto's Catch Can a true plug-n-play upgrade. All the necessary brackets and hardware are included, with no cutting or extra modifications required.

    Application. This Mishimoto Passenger Side Baffled Air/Oil Separator with Red Silicone Hoses is designed for use on all 2015-2017 GT Mustangs equipped with the Coyote 5.0L 4 valve DOHC V8 engine. Installs on the passenger side, same side as the PCV valve.

      Mishimoto catch can

      Great product. Well made. Love the hoses. Might be a challenge to empty but it has a 3/8” plug in the bottom. I’ll run a hose with a drain plug to the bottom. Should solve that problem.

      Looks good under the hood

      Best looking oil catch can for s550 mustang. Had to watch an install video on YouTube as a little confusing at points but not to bad. Took about an hour. Be careful when removing the stock oil lines and adding the new oil lines they are tricky if you never done it you Can break somthing if you don’t know what you are doing. My next oil change i will empty it out to see what all it caught

      Looks good but not so easy to empty out

      Mishimoto put a good bit of thought into it but still came up short with their hard to empty design. Placement was ideal but as far as using the catch can for its purpose of catching and emptying oil it really is a pain having to remove both hoses first. Looking for another design

      Install took maybe 30 minutes taking my time. It's a really tight fit next to the washer fluid bottle and the radiator. A little too tight. But it looks great.

      Amazing fit

      This catch can i can say by far has the most thought put into it. It looks aftermarket, but at the same time looks original. It looks like a professional upgrade to an engine and that red just pops. I cant wait to see how it looks under the supercharger im adding on! definitely buying more mishimoto.

      Great, but...

      Installation was easy, less than 20 minutes. Looks great. After having it installed a month and a half on a 2017 GT PP with 34 miles on it, I can confirm that it is working well; plenty of sludge caught after 500 miles. However, my biggest complaint is that their is not enough room to reach in and unscrew it for regular emptying. And I have SMALL hands. I had to remove both hoses and unmount the unit from the metal bracket. A real pain in the... Could be different on 15 and 16 model years, but on the 2017 GT PP – impossible. Additionally, the can is very tight against a nearby wiring harness which I don't care for, but seems ok.

      Mishimoto Direct Fit Baffled Oil Separator System

      An excellent product that looks really nice under the hood especially if you order one with red or blue hoses. The mounting bracket is a nice addition. It secures the catch can and keeps it from hanging like a limp noodle. It does cost a little more than other oil separators but considering the quality it is worth it. Installation was super easy, it should not take you anymore than thirty minutes.
