The Mishimoto Baffled Oil Catch Can was designed to separate oil particles from the PCV air that would normally have just been routed back to your intake.
Custom grooves in the catch can's inlet turbulates the air longer and ensures all the oil sinks to the bottom of the can, leaving nothing but clean air to pass through the 40 micron bronze filter to the intake. An internal baffle keeps the collected oil from splashing around under race conditions. Mishimoto has developed a carbon fiber oil catch can to make sure you're getting the most out of your performance parts.
Over time harmful oil will build up inside the turbocharger, intake manifold, intercooler and piping. A Mishimoto Carbon Fiber Oil Catch Can will prevent this from happening while its sleek carbon fiber exterior will add a touch of style to your engine bay.
The Mishimoto Aluminum Oil Catch Can prevents the harmful buildup of oil inside of the turbocharger, intake manifold, intercooler, and piping. This catch can prevents oil from getting into pressurized turbo plumbing and stops oil vapors from getting into the intake system that would ultimately lead to lower combustion temperatures and reduced overall efficiency. The Mishimoto STi oil catch can is designed and engineered to eliminate harmful blow-by vapors from re-entering your engine. The EJ25 in the STi is known for producing blow-by gases during both normal and severe driving, especially when boost levels are increased.
The slower velocity leads to greater oil separation from the pressure stream. On the top, a thick Viton o-ring seals the can. Every o-ring in our AOS is formed from Viton which offers superior temperature and chemical resistance.
The Subaru EJ engine has 3 ports that vent crank pressure: one on each cylinder head, and another on the top of the block. Each engine vent port receives its own connection to the AOS.
By giving each engine port its own entrance to the AOS IAG has allowed for more effective and faster excavation of crankcase pressure.
Additionally, this reduces overall system pressure. The AOS has an approximate 1 liter of holding capacity. The bottom of the AOS is shaped like a snail, redirecting positive crank pressure into the same swirl pattern produced by the 3 side ports.
This allows maximum oil drainage, while separating oil from the air in all the venting ports. Why not use a catch can? Catch cans require regular maintenance and manual draining for proper operation. If the catch can is not drained often it may reintroduce oil into the intake when it overflows or create a mess in the engine bay. The drain port is under the same crankcase pressure as the other ports that are on the side of the AOS.
Under normal, off boost driving the weight of the collected oil will easily overcome the pressure in the drain line. The unique snail design allows the system to breathe without disturbing the swirl pattern. This cast aluminum can holds more heat which maximizes the evaporation of any condensation collecting inside of the can. The hotter the AOS, the less condensation will collect inside and mix with the oil.
The center bracket allows for adjustable mounting. If your engine bay changes, you can easily change how and where you mount the AOS. The V3 AOS body features a greater number of mounting holes enabling a wider range of adjustment. A single, laser-cut, mounting bracket is included that fits nearly all applications and configurations.
A laser cut harness relocation bracket is also included. The bracket allows the engine harness connector to be moved forward for additional clearance. A: In stock configuration, the un-baffled crankcase pressure is re-circulated back into the intake stream.
This can be harmful for two reasons:. The most significant of these factors are boost pressure, piston to cylinder wall clearance and oil viscosity. Smaller factors include ambient temperature, engine temperature, piston ring condition, and valve guide condition.
Most catch cans require you to drain the contents out manually. By nature, a turbocharged boxer engine will produce significantly more oil in the CCVS than other engines of similar displacement. Q: Which AOS is right for my vehicle? The Street Series AOS provides optimal oil separation and venting performance for vehicles, including unregulated competition applications, up to WHP and those fueled by E85 or other high-ethanol fuel blends.
The Street Series AOS protects from ethanol caused oil dilution and resulting extremely frequent oil change requirements. Pulling vacuum via the Street Series recirculating design to the inlet is ideal for ethanol fueled competition vehicles, removing ethanol vapors from the crankcase and returning them to the intake system for complete combustion. IAG is not offering any Competition only components for installation on street driven or regulated applications.
Superb build quality, thoughtful and thorough install directions. Previous AOS drained to oil fill almost blew up my car on the Dyno heavy smoke after pulls. Replaced with IAG and problem was solved, and looks better too. Definitely going install on my other EJs. All packages include shipping insurance in case they are lost or damaged. USPS shipping times are estimated and not guaranteed. UPS tracking numbers are automatically generated when a package ships and the number is sent to the email address you provided.
If a package contents is damaged during shipping please notify the shipping driver and file a claim with the shipper. You have 14 days to inspect your shipment and contents. After that period of time, IAG is no longer responsible for missing items. It includes mounting brackets specific to the WRX, hoses, and all the required hardware for an easy installation. Inside the cans, an air diverter causes turbulance in the air to improve oil separation, and a micron bronze filter keeps the air clean as it leaves the cans.
The cans have baffles inside that prevent oil from splashing up and making its way back into the system. Another catch can system from Mishimoto, this one is simpler and more affordable. It has a single catch can for the PCV system. This provides most of the benefit of the dual catch can system, but it's easier to install and costs less.
The catch can has internal baffling to keep the separated oil down in the can. This helps to insure the air that passes through is as clean as possible. An air oil separator does more than a catch can, but it's main job is still keeping the intake tract clean. Rather than just collecting the oil from the PCV system, requiring a can to be emptied occasionally, an AOS returns the oil back to the car's oil pan.
This means there's no added maintenance, just regular oil changes will do. Many people prefer an AOS, since there's no need to worry about the cans filling with oil and no added maintenance. It also connects to the coolant lines. This is because condensation tends to form inside the AOS otherwise due to the difference in temperature between ambient and the crankcase gasses.
