CTS Turbo Product Description

CTS Turbo is proud to release our B-Cool DSG Oil Housing for the VW Golf R and 8V.2 S3/RS3/8S TTRS 7-speed DSG (DQ381 and DQ500).  The OE plastic filter housing is quite fragile and is know to become brittle and crack over time going through many heating and cooling cycles.  Each CTS Turbo B-Cool DSG Oil DSG 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 in the oil. This helps maintain the viscosity in the oil to keep optimal performance. Replaces part number 0BH325159.
