We love these catch cans for most turbo or supercharged applications. Comes with 12an inlets and a open mesh vent to atmosphere design with all the flow. The Gen3 Catch Can features -12 ORB female ports on the lid and a -8 ORB female port on the drain. The Catch Can is supplied with -12 ORB male to -12 AN male adapters and a -8 ORB male drain plug.
