Engine vents through the included billet aluminum oil fill cap (with PCV valve) and into the catch can, then the air travels to the intake manifold. This closed loop system is effective at keeping crankcase blow-by oil and contaminants out of the intake manifold/blower on the CTS-V. Kit includes all fittings, hoses, brackets, etc. for an easy bolt-on installation.
