i have a Greddy type rs adjustable bov with everything you need even the adapter for the intercooler. the bov can vent atmospheric if you want and it sounds good it also has the plug for bov return hose, or you can recirculate it if you want because it comes with the recirculation kit. there is nothing wrong with this bov but i just need some money for classes. so my loss is your gain. first 100 dollars takes it shipped.
