CTS Turbo is proud to release our B-Cool Billet 01E DSG Oil Filter Housing. The OE plastic filter housing is quite fragile and is know to become brittle and crack over time. Each CTS Turbo B-Cool Billet 01E DSG Oil Filter Housing is constructed in house from T6061 Aluminum. Not only does the B-Cool filter look good, but it works great. We have engineered cooling fins into our design to act as a heatsink, which dissipates heat from the DSG fluid. Installation is very straight forward and only required basic hand tools.
