The Billet Breather Block Off Kit for 8J Audi TTRS 2.5 TFSI is designed to remove the “shortcut” for oil to directly enter the intake manifold, forcing crankcase ventilation to go through an aftermarket catch can setup and also allowing for a boost tap or intake injection point.
Once installed, along with the 034Motorsport Billet Catch Can, crankcase oil will not be allowed to enter the intake manifold. This will eliminate oil consumption from crankcase evacuation as well as improve combustion and prevent smoking from the tailpipe.
