Billet Blow-Off Valve System, Cobalt SS/TC: Includes Open Discharge Billet BOV and hardware for Hahn Charge Air Piping. Offered two ways: Open Discharge and Recirculating.
As the name implies, the Open discharge simply vents the bypassed air under the hood.
Our Recirculating version is a clean solution to a recirculating system which will take the air the blow-off valve discharges and direct it back into the turbo inlet. This will provide faster turbo spool after upshifts, and is generally a smoother operating system as compared to external or open discharge. This version includes piping and hardware to duct air back into our CoolRam intake system for Cobalt.
