Has anybody put SLK shocks on their XF? Are there any issues?

Bilstein B6 carries a different part number and the lower mount appears to be painted yellow instead of left black. Is there any difference at all in the fitment? Are they tuned differently in any meaningful way?

The SLK version is slightly cheaper, and I'd rather not spend extra if they are essentially the same.

I know most parts in the chassis and drive train are directly swappable. One difference I found straight off was the air filter.
