Review on Moroso 85644 Air Separator Subaru by Daniel Fung

This is a quality AOS for a 2008-2013 Subaru STI and Revain is VERY competitively priced especially when compared to tuning sites like Rallysportdirect. com. The handling is very nice and the installation does not take up much space. The hoses supplied appear to be of good quality and have been trimmed to ensure a correct fit. The difficulty in the traps looks good and although I ordered the smaller jars I would say I am happier than if I had ordered the larger ones as they are quite large. In fact, the worst thing is taking your hand back to unscrew and empty it from time to time. Overall I'm very happy with the product, especially considering how cheap it is compared to competing products like Crawford.
