CTS TURBO Billet Oil Filter Housing DQ381 / DQ500

CTS Turbo introduces the B-Cool Billet DSG Oil Filter Housing – a high-quality aluminum replacement for the factory plastic housing for DQ381 and DQ500 DSG transmissions.

The original plastic housing often becomes brittle and cracks after repeated heating and cooling cycles. CTS solves this problem with a massive CNC machined construction made from T6061 billet aluminum.

🔧 Key Advantages

✔ Made in Canada from billet T6061 aluminum
✔ Integrated cooling fins (heatsink design)
✔ Aids in dissipating heat from the DSG oil
✔ Maintains more stable oil viscosity
✔ Hard anodized black coating – fade resistant
✔ Uses the original OEM O-ring
✔ Precise OE thread – direct installation

Replaces OE number: 0BH325159

🧊 Why is the upgrade important?

DSG transmissions operate at high temperatures, especially during:

• Stage 2 / Stage 3 vehicles

• Launch control

• Track driving

• Towing and aggressive driving

The cooling fins act as a radiator and help dissipate heat, which:

• Maintains optimal viscosity

• Reduces thermal stress

• Improves transmission reliability

🚗 Compatibility

• Audi RS3 8V – 2.5T

• Audi TT RS 8S – 2.5T

• Audi RSQ3 F3 – 2.5T

• Audi S3 8V Facelift

• Volkswagen Golf R Mk7.5
