In collaboration with IAG we are excited to offer a unique selection of colors for the V3 AOS! Here you are looking at the World Rally Blue offering which is by far the most popular Subaru Color with hints of pearl which will accent your engine bay nicely!\u003c\/p\u003e\n\u003cp\u003eThe IAG Air \/ Oil Separator (AOS) is a smart upgrade for your Subaru. Developed over years of rigorous testing on various standard and competitive applications, the IAG AOS provides unmatched protection for your 2015-2021 WRX and 2014-2018 Forester XT 2.0L FA engine. Our exclusive AOS design incorporates a 1-liter cast aluminum swirl pot canister that significantly improves oil separation from the PCV system before returning PCV gasses to the intake. The durable and lightweight aluminum housing provides improved ventilation, while incorporating the use of an intelligent baffle design that sets it apart from the competition. The IAG AOS works with all fuel types, enhances crankcase ventilation, and seamlessly integrates with standard ECU settings.\u003c\/p\u003e\n\u003cp\u003eOil in the engine's intake tract may lead to various negative effects. Preventing oil from entering the engine intake is vital to prevent premature mechanical issues and to uphold optimal performance in your Subaru. Oil coated components in the intake, intercooler and plumbing can lead to the breakdown of the rubber and silicone hose connections. Once the oil enters the intake tract, the oil can access the intake manifold and then the engine’s combustion chamber, potentially triggering detonation, pre-ignition, excessive emissions, smoke, power loss, reduced fuel efficiency, and even engine damage or complete engine failure.\u003c\/p\u003e\n\u003cp\u003eUnlike ordinary catch-can systems, the IAG Air \/ Oil Separator functions without the need for routine draining or maintenance. The separated oil gathers along the walls of the AOS canister, then drains gradually into the engine's crankcase. The large body of the IAG AOS eliminates the risk of overflow by allowing the oil to drain slowly, whereas smaller catch cans are unable to keep up and often require manual draining. The exclusive heating system on the IAG AOS ensures that the gathered oil remains free of sludge, reducing the possibility of reintroducing it back into the engine.\u003c\/p\u003e\n\u003cp\u003eThe IAG Air \/ Oil Separator uses a unique baffle system to collect and drain the oil from your engine's PCV gasses back to the crankcase. The AOS body's inlet hoses create an internal gas vortex, which then filters through the baffles, trapping the oil and allowing the gas to escape from the top of the AOS canister. The OEM PCV function is retained, so you still get the benefit of intake manifold vacuum helping to draw gasses through the system.\u003c\/p\u003e\n\u003cp\u003eThe IAG Air \/ Oil Separator integrates with the OEM PCV system, while increasing its capacity. In ethanol-fueled applications, it prevents oil dilution and lubrication issues by capturing fuel vapors from the oil and reintroducing them for combustion. IAG's AOS prevents oil from entering the intake and fuel dilution of the engine's lubrication system.\u003c\/p\u003e\n\u003cp\u003eCrafted with a lightweight yet sturdy aluminum housing, the IAG Air \/ Oil Separator is even lighter than our previous AOS iterations. Whether you're drag racing or hitting the track in your Subaru, we value the importance of weight savings. This is why we've fine-tuned and lightened this AOS design to enhance your Subaru's overall performance, guaranteeing you get the best results every time you race or hit the track.\u003c\/p\u003e\n\u003cp\u003eThe IAG Air \/ Oil Separator features a proprietary heating system that capably handles issues frequently encountered in lower-quality catch cans. Unlike inferior designs that allow hot PCV gasses to pass through cold passages, leading to condensation mixing with oil and causing sludge, IAG's improved design is linked to the vehicle's cooling system. This enables the transfer of heat from the engine into the AOS canister. By heating the AOS canister to the engine's temperature, condensation and associated buildup are significantly diminished or completely eliminated.\u003c\/p\u003e\n\u003cp\u003eIAG's Air \/ Oil Separator comes with a complete set of custom-length SAE Quick Connection lines, simplifying the installation process and minimizing the risk of leakage as a result of a more dependable and secure connection compared to standard hose clamps. Once installed, our AOS system features a polished factory-like appearance that matches your Subaru’s engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTrue 360 Degree Rotating Breather Port\u003c\/li\u003e\n\u003cli\u003eDual Breather Ports\u003c\/li\u003e\n\u003cli\u003eGreater Pressure Stream Oil Separation\u003c\/li\u003e\n\u003cli\u003eCompact Cast Aluminum Design\u003c\/li\u003e\n\u003cli\u003eApproximate 1 Liter Holding Capacity\u003c\/li\u003e\n\u003cli\u003eAluminum Body is finished in powdercoat\u003c\/li\u003e\n\u003cli\u003eUnique Baffling Controls Crankcase Pressure\u003c\/li\u003e\n\u003cli\u003eReturns Oil To The Engine\u003c\/li\u003e\n\u003cli\u003eNo Maintenance or Manual Draining Required\u003c\/li\u003e\n\u003cli\u003eIncludes all fitting required for installation\u003c\/li\u003e\n\u003cli\u003eIncludes unique billet aluminum coolant swivel fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Instructions: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca title=\"IAG Air \/ Oil Separator (AOS) - PDF Instructions for 2017-21 Subaru WRX\" href=\"https:\/\/www.iagperformance.com\/content\/instructions\/IAG\/IAG-ENG-7187\/iag-aos-2017-21-wrx.pdf\" target=\"_blank\" rel=\"noopener\"\u003eIAG Air \/ Oil Separator for 2017-21 WRX - PDF Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca title=\"IAG Air \/ Oil Separator (AOS) - PDF Instructions for 2015-16 Subaru WRX\" href=\"https:\/\/www.iagperformance.com\/content\/instructions\/IAG\/IAG-ENG-7187\/iag-aos-2015-16-wrx.pdf\" target=\"_blank\" rel=\"noopener\"\u003eIAG Air \/ Oil Separator for 2015-16 WRX, 2014-18 Forester XT - PDF Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":51530938057026,"sku":"IAG-ENG-7187WRB","price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0782\/9294\/3170\/files\/iag-performance-limited-edition-v3-street-series-air-oil-separator-aos-world-rally-blue-2015-2021-wrx-iag-eng-7182wrb-474527.jpg?v=1763155310","url":"https:\/\/autospecdesign.com\/products\/iag-performance-limited-edition-v3-street-series-air-oil-separator-aos-world-rally-blue-2015-2021-wrx","provider":"AutoSpec Design","version":"1.0","type":"link"}
