Can is Heated for Cold Climates and Short Drives. The Crawford Performance Air/Oil Separator (AOS) is the original solution to Subaru’s notorious oiling system issues. Although the technology was pre-existing with other vehicle brands such as Porsche, Crawford Performance is the inventor of the first system specifically for Subaru. No other AOS on the market employs the same technology. How does it work? The built in AOS that comes factory in Subaru Engines is only semi-efficient at stock power levels. Any added power/stress/heat and G-Forces increases the amount of excess oil that ends up in your intake. Due to the fact the oil is heavier than water and you’re dealing with a horizontally-opposed engine, the oil can only end up in one place: coating the tops of your pistons. Since oil is naturally combustible, this causes irregularities with the controlled explosion that happens in this environment, subsequently creating multiple explosions. Another word for this is detonation an engine killer. Stop the oil from ever getting there with the Crawford Air/Oil Separator. Having a secondary system is your fail-safe for detonation that is un-related to a poor tune. You will also consume less oil and help maintain the ultimate mixture in your cylinders to maximaize your power output.

Crawford Air Oil Separator 02-07 Subaru WRX/STi TMIC

Wednesday, July 19th, 2017
Crawford Air Oil Separator 02-07 Subaru WRX/STi TMIC

Crawford Air Oil Separator 02-07 Subaru WRX/STi TMIC

This listing is for the newer, black version! Drawing on their 35 years of racing knowledge, the Crawford Performance Closed Loop Air/Oil Separator was engineered and designed to keep motor oil where it belongs inside the motor and out of the intake system. In the stock configuration, the crankcase is vented to the intake system in three different places. Each of these vents have a baffle system built within the motor to minimize the transfer of oil to the intake, but some oil can still make its way into the combustion chambers. When the oil enters the combustion chambers, it effectively lowers the octane of the fuel, leading to detonation. Crawford’s Air/Oil Separator effectively removes the oil from the air coming out of the engines ventilation system via a two stage process. The first step in the process is a large volumetric swirl pot. The function of the swirl pot is to use centrifugal force to remove the oil from the air. The air is then passed through a second chamber (see second step below), and extracted through the top of the AOS. Gravity then sends the remaining oil down the walls of the swirl pot and collects in the bottom of the AOS. The second step involves a second chamber located within the first chamber. As the separated air moves up inside the AOS, it must enter the second chamber before it can vent out the top of the AOS. The function of the secondary chamber is to remove any residual oil that may have made its way up the swirl pot. The secondary chamber also has a drain to return any separated oil back to the engine. Crawford’s Version 2 AOS also incorporates an internal heater to keep the AOS operating at the proper temperature. The coolant line that runs from the turbo to the engine is now re-routed through the AOS. The effectively equalizes the temperature between the AOS and the engine to avoid condensation which can occur within any AOS. This heater also makes sure the vaporized water leaving the motor makes its way through the AOS in vapor form, rather than condensing back into a liquid. This is a MUST in cold weather and a bonus for any climate. NO OTHER AOS ON THE MARKET EMPLOYS THIS TECHNOLOGY! Crawford Part Number — S0714-1.

IAG Performance RED Competition Air Oil Separator AOS 06-07 WRX & 04-07 STi

Tuesday, July 18th, 2017
IAG Performance RED Competition Air Oil Separator AOS 06-07 WRX & 04-07 STi

IAG Performance RED Competition Air Oil Separator AOS 06-07 WRX & 04-07 STi

IAG Performance RED Competition Air Oil Separator AOS 06-07 WRX & 04-07 STi

IAG Performance RED Competition Air Oil Separator AOS 06-07 WRX & 04-07 STi

Up For Sale is an IAG Performance Competition AOS in RED! BE SURE TO NOTE YOUR YEAR/MODEL OF CAR IN THE NOTES TO ENSURE PROPER FITMENT! The IAG Performance Competition Series billet aluminum Air / Oil separator (AOS) vents crankcase vapors to the atmosphere. The design is based on years of service on racing and high horsepower Subaru’s. The AOS’s approximate 1 liter capacity, fully heated housing, superior breathing and unique patent pending baffle design sets it apart from the rest. 180° Breather Port Rotation For Install Ease. Greater Pressure Stream Oil Separation. Notice the large breathing port? At first glance you might think this is excessive, however our reasoning is grounded in simple physics. As air and particles of oil enter into the AOS, the largest particles of oil will collect on the inner surface of the can and drain to the bottom, but the smallest particles will remain suspended in the pressurized stream. As the air makes its way through the multi-stage baffle system, gravity pulls oil from the air. By increasing the diameter of the breather opening on the top of the AOS, we have drastically decreased the exit velocity of the crankcase vent (CCV) stream. The slower velocity leads to greater oil separation from the pressure stream. A total of 9 mounting holes give the breathing port a full 180° of rotation. On the bottom, 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. Large Billet Alumium Design. Approximate 1 Liter Holding Capacity. Integrated 3 Port Billet Hose Barbs. Aluminum Body Powered Coated Black or Red. The side of the Air Oil Separator features 3 port billet hose barbs. There are NO plastic fittings that require thread tape to seal. 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 we have allowed for more effective and faster excavation of crankcase pressure. Additionally this reduces overall system pressure. With a 4″ OD and 5.75″ height, the AOS has an approximate 1 liter of holding capacity. The larger the AOS, the more power you can safely make without having to worry about the AOS overfilling. Unique Baffling Controls Crankcase Pressure. No Maintenance or Manual Draining Required. 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. Allowing maximum oil drainage while separating oil from the air in all the venting ports. Why not use a catch can? Unmodified Subaru’s may require catch can draining as often as every few weeks. Heavily modified race cars may be as often as every race. Our AOS collects oil and actively drains the oil to the crankcase. 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. However, under heavy boost (especially on higher powered engines) the crank pressure will push back up the drain with the same air/oil mixture that is seen on the side ports. The unique snail design allows the system to breath without disturbing the swirl pattern. AOS FITTINGS All fittings supplied with the AOS are anodized aluminum and feature Viton sealed ORB fittings. AOS HOSE The supplied coolant hose is built to exceed SAE J20R3 standards. It will withstand coolant temperatures up to 300°F. The oil vapor hose is designed to withstand oil and fuel vapors, exceeding SAE J30R7 standards. Heated By Engine Coolant. Reduces Moisture & Oil Mixing. The back plate of the AOS features a unique coolant routing system that heats the entire AOS to the same temperature of the engine. This maximizes the evaporation of any water collecting inside of the can. The hotter the AOS, the less water will collect inside and mix with the oil. Multi-point Adjustable Mounting Bracket. The center bracket allows for adjustable mounting. If your engine bay changes, you can easily change how and where you mount the AOS. 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. AOS IN THE BOX. Hardware, Lines & Fittings Included. Your AOS will arrive to you completely assembled and ready for immediate installation. However, the entire unit can be broken down for cleaning. With a single allen wrench, you can remove 4 bolts and the AOS easily separates into individual pieces. FAQ: Q: Why do I need an AOS? A: In stock configuration, the un-baffled crank case pressure is re-circulated back into the intake stream. The more oil vapor that is sucked back into the engine, the more likely you are to experience engine knock (also referred to as detonation) that can destroy an engine. 2 Oil vapors cause oil & carbon build up over time. The intercooler, intake manifold & intake valves suffer the worst. This oil vapor can create air turbulence that leads to various running issues. Q: What are the factors that cause oil in crank case vent system (CCVS)? A: There are a variety of factors that determine how much oil will be in the CCVS. 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. Q: Are there any risks to using the IAG billet AOS? A: If your AOS is properly installed, there are not any risks. Q: What’s the difference between a catch can & the IAG AOS? A: Catch cans are a air/oil separator that does not actively drain the collected oil back into the engine. Most catch cans require you to drain the contents out manually. While acceptable on some engines that produce little oil in the CCVS, the Subaru EJ engine is not this type of engine. By nature, a turbocharged boxer engine will produce significantly more oil in the CCVS than other engines of similar displacement.
