We designed the AOS with detailed internal passages and a two stage separation system. The first separates the larger oil droplets from the air and the second stage separates the remaining smaller droplets from the air. The result is a fully recirculated maintenance free system, with no oil smell. The oil that is extracted is returned back to the engine so you never have to worry about emptying a can or an overflowing can emptying itself into your turbo inlets and engine bay. Systems that don't recirculate will emit a smell that your climate control system will recirculate into the car, that doesn't exist in the stock form or with our system.
