Product Details

CTS Turbo is proud to release their B-Cool DSG Oil Housing for the S3/RS3/TTRS/Golf R with 7-speed DSG (DQ 381 and DQ500).  The OE plastic filter housing is quite fragile and is known 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.  CTS have engineered cooling fins into their design to act as a heatsink, which dissipates heat in the oil. This helps maintain the viscosity in the oil to keep optimal performance.

  • Hard anodized black for stealth and longevity, will not discolour or fade
