In these cases, an ordinary small catch can may quickly fill with oil and not be adequate. Like the Radium Engineering , 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.\u003c\/p\u003e\u003ch2 style=\"text-align:center;\"\u003eBENEFITS\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEffectively raises the octane and increases engine performance with cleaner inlet air\u003c\/li\u003e\n\u003cli\u003ePrevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc.\u003c\/li\u003e\n\u003cli\u003eLowers hydrocarbon emissions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":48062393352410,"sku":"RAD20-0607","price":427.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/ds_GPWQ_20-0607__72508.1725657917.1280.1280.jpg?v=1781530001","url":"https:\/\/www.iagperformance.com\/products\/radium-engineering-air-oil-separator-return-kit-for-2002-14-subaru-wrx-04-21-wrx-sti-04-13-fxt-20-0607","provider":"IAG Performance","version":"1.0","type":"link"}
