Developed through years of meticulous testing on standard and competitive applications, the design of the AOS offers unparalleled protection for your engine. This AOS features a 1-liter swirl pot canister made of cast aluminum. This construction significantly enhances the separation of oil from the PCV system before the PCV gasses are directed back to the intake system. The Air Oil Separator features an aluminum housing that has superior ventilation, and it incorporates an exclusive baffle design that sets it apart from the competition. The IAG AOS works with all fuel types, optimizes crankcase ventilation, and seamlessly integrates with standard ECU settings, so no tuning is required.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-ed570c3d-2af1-43da-b2a2-5a88da881794\"\u003e\n\u003cdiv class=\"shg-row\" data-col-grid-mode-on=\"\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-1b14522e-13d3-4f1a-ba6e-eee2ed6ebc0a\" class=\"shg-c shg-align-center\"\u003e\n\u003cdiv class=\"shogun-heading-component\" data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInLeft\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]'\u003e\n\u003ch2\u003eKEEPS OIL OUT OF THE INTAKE\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-d69bf002-35e0-47d3-ad61-94abac944db6\" class=\"shg-c\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eThe presence of oil within the engine's intake tract brings about a range of adverse effects, so preventing oil from entering the engine intake is crucial for avoiding premature mechanical issues and maintaining optimal performance. Initially, the oil coats the internal components of the intake, intercooler, and piping, which can potentially harm or prematurely deteriorate rubber or silicone hoses, eventually leading to compromised connections. Once the oil enters the intake tract, it has access to the intake manifold and then the engine’s combustion chamber. Oil inside the chamber has the potential to trigger detonation, pre-ignition, excessive emissions, smoke generation, power loss, reduced fuel efficiency, and in extreme cases, severe engine damage or even complete engine failure.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-9bbbfccb-ca86-46d6-8601-cf14e19318bf-root\"\u003e\n\u003cdiv class=\"shg-image-margin-container-s-9bbbfccb-ca86-46d6-8601-cf14e19318bf\" id=\"wrap-s-9bbbfccb-ca86-46d6-8601-cf14e19318bf\"\u003e\n\u003cdiv class=\"s-9bbbfccb-ca86-46d6-8601-cf14e19318bf shg-align-container\"\u003e\n\u003cdiv class=\"shg-c s-9bbbfccb-ca86-46d6-8601-cf14e19318bf shogun-image-container shg-align-center\" id=\"s-9bbbfccb-ca86-46d6-8601-cf14e19318bf\"\u003e\n\u003cdiv class=\"shg-image-content-wrapper\"\u003e\u003cimg srcset=\"https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/180x\/ 180w,https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/360x\/ 360w,https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/720x\/ 720w,https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/900x\/ 900w,https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/1080x\/ 1080w,https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/1200x\/ 1200w\" sizes=\"100vw\" src=\"https:\/\/i.shgcdn.com\/2f772396-2797-420c-84f0-d5157441dffa\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/\" alt=\"Oil in the intake tract\" class=\"shogun-image\" decoding=\"async\" loading=\"lazy\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-995c67ba-cef6-4ac9-a1cb-4f0749e98750\"\u003e\n\u003cdiv class=\"shg-row\" data-col-grid-mode-on=\"\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e-root\"\u003e\n\u003cdiv class=\"shg-image-margin-container-s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e\" id=\"wrap-s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e\"\u003e\n\u003cdiv class=\"s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e shg-align-container\"\u003e\n\u003cdiv class=\"shg-c s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e shogun-image-container shg-align-center\" id=\"s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e\"\u003e\n\u003cdiv class=\"shg-image-content-wrapper\"\u003e\u003cvideo autoplay=\"autoplay\" loop=\"loop\" muted=\"\" playsinline=\"\" preload=\"none\" class=\"shogun-image\"\u003e\u003c\/video\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-d306c2a4-e090-4da1-ba24-16e2faeec19b\" class=\"shg-c shg-align-center\"\u003e\n\u003cdiv class=\"shogun-heading-component\" data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]'\u003e\n\u003ch2\u003eNO MAINTENANCE NEEDED\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-51c1c6dd-6fdb-4455-919b-4ddc7def246a\" class=\"shg-c\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eThe IAG AOS is designed for effortless upkeep.

As the factory PCV remains active, this allows the engine to generate a vacuum in the AOS assembly to draw out even more of the PVC gasses.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-df1ec5f2-84a9-47a7-84a1-31716943e260-root\"\u003e\n\u003cdiv class=\"shg-image-margin-container-s-df1ec5f2-84a9-47a7-84a1-31716943e260\" id=\"wrap-s-df1ec5f2-84a9-47a7-84a1-31716943e260\"\u003e\n\u003cdiv class=\"s-df1ec5f2-84a9-47a7-84a1-31716943e260 shg-align-container\"\u003e\n\u003cdiv class=\"shg-c s-df1ec5f2-84a9-47a7-84a1-31716943e260 shogun-image-container shg-align-center\" id=\"s-df1ec5f2-84a9-47a7-84a1-31716943e260\"\u003e\n\u003cdiv class=\"shg-image-content-wrapper\"\u003e\u003cimg srcset=\"https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/180x\/ 180w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/360x\/ 360w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/720x\/ 720w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/900x\/ 900w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/1080x\/ 1080w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/1200x\/ 1200w,https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/-\/resize\/1920x\/ 1920w\" sizes=\"100vw\" src=\"https:\/\/i.shgcdn.com\/73d30778-5c10-47a0-aa63-107365e7268a\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/better\/\" alt=\"What's Inside and AOS\" class=\"shogun-image\" decoding=\"async\" loading=\"lazy\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-92b63657-69a3-4ee0-83f5-f5725b492dd5\"\u003e\n\u003cdiv class=\"shg-row\" data-col-grid-mode-on=\"\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-981f637c-bce5-4a82-8214-a5e48969ff80-root\"\u003e\n\u003cdiv class=\"shg-image-margin-container-s-981f637c-bce5-4a82-8214-a5e48969ff80\" id=\"wrap-s-981f637c-bce5-4a82-8214-a5e48969ff80\"\u003e\n\u003cdiv class=\"s-981f637c-bce5-4a82-8214-a5e48969ff80 shg-align-container\"\u003e\n\u003cdiv class=\"shg-c s-981f637c-bce5-4a82-8214-a5e48969ff80 shogun-image-container shg-align-center\" id=\"s-981f637c-bce5-4a82-8214-a5e48969ff80\"\u003e\n\u003cdiv class=\"shg-image-content-wrapper\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/907c4661-33bc-4dca-8402-d642cb397019\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" alt=\"AOS Improves the PCV System\" class=\"shogun-image\" decoding=\"async\" loading=\"lazy\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-cbd15ec9-c785-4c20-98c5-6597e3901571\" class=\"shg-c shg-align-center\"\u003e\n\u003cdiv class=\"shogun-heading-component\" data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]'\u003e\n\u003ch2\u003eIMPROVES UPON THE OEM PCV SYSTEM WITH NEW CHECK VALVE\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-24219cd8-a7fd-48cc-acce-87bc9dc85f4b\" class=\"shg-c\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eThe AOS integrates with the OEM PCV system, while also providing a boost to its capacity.
