S54 D300 Exhaust Hub
As an alternative to our factory Cryo hub, the D300 hub is a stock BMW hub that has been machined and modified with heavy-duty oil pump tabs for maximum durability. The oversized tabs are designed to work with the original oil pump disc, so drilling smaller holes in the disc is NOT required. The D300 will also work with our rebuilt vanos without any other modifications.
Return your old hub with the supplied prepaid shipping label for a $50 core refund.
