The Delicious Tuning Air / Oil Separator (AOS) is a plug & play installation that fits most applications (NA, Supercharger, Turbo) on the 86 platform. One of the primary concerns on the development of our AOS was to ensure that all emission control devices are working as intended and nothing has been removed from the vehicles breather system, (including the PCV). While we may not be the first to create an AOS, we saw a need for a simple plug-n-play system for almost all forced induction applications that will also work with naturally aspirated vehicles (for those looking to upgrade down the road). The number one reason to have an AOS is to remove the oil ingested by the engine that comes from the OEM breather system. Below are a list of reasons why this is a good thing.
