In these cases, an ordinary small catch can may quickly fill with oil and not be adequate. \u003cbr\u003e\u003cbr\u003eLike the Radium Engineering Subaru Dual Catch Can Kit, the AOS (Air Oil Separator) kit is responsible for keeping blow-by oil and other pollutants out of the intake pipe, manifold, turbocharger, and intercooler during all engine loads. The main difference is that an AOS-\"R\" system \"returns\" what is collected back into the oil pan so there is no servicing required.\u003cbr\u003e\u003cbr\u003eThe built-in heater keeps water from condensing in the AOS, and because water is more dense than oil, there is an integrated water trap found around the bottom perimeter of the can. This prevents water from descending into the oil pan if ever present.\u003cbr\u003e\u003cbr\u003eFurthermore, because the water is trapped against the heater, it will eventually boil and evaporate out of the system. The AOS is constructed of three CNC machined sections that screw together and are sealed with o-rings.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eMeasurements:\u003c\/span\u003e\u003cbr\u003e• AOS Height: 6.94\" (top of dipstick to bottom of AOS)\u003cbr\u003e• AOS Diameter: 3.45\" Round \u003cbr\u003e• AOS Capacity: 20.3 oz (600mL)\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eBenefits:\u003c\/span\u003e\u003cbr\u003e• Effectively raises the octane and increases engine performance with cleaner inlet air \u003cbr\u003e• Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc. \u003cbr\u003e• Lowers hydrocarbon emissions\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eIncludes:\u003c\/span\u003e\u003cbr\u003e• Machined aluminum Radium Engineering Air Oil Separator\u003cbr\u003e• Specially designed mounting bracket (see note at bottom of page)\u003cbr\u003e• All necessary SAE J30R7 rated PCV\/Emissions hose\u003cbr\u003e• Coolant hoses and fittings\u003cbr\u003e• All necessary aluminum fittings and hose-ends\u003cbr\u003e• Stainless steel mounting hardware\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003eProduct Notes:\u003c\/span\u003e\u003cbr\u003eOld part number design was 20-0207-08\u003cbr\u003e \u003ca href=\"https:\/\/stmtuned.com\/collections\/radium-products\" style=\"color: #afafaf;\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more Radium Products\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"Radium","offers":[{"title":"Default Title","offer_id":50563159064918,"sku":"RAD-20-0607","price":516.17,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/20-0607-radium-aos-subaru-sti-2015-air-oil-separator-1.jpg?v=1749209888","url":"https:\/\/www.speed-addicts.com\/en\/products\/radium-aosr-air-oil-separator-2008-wrx-sti","provider":"Speed Addicts","version":"1.0","type":"link"}
