This complete E46 Finned Differential Cover Kit contains all of the parts required to be installed on any E46 323i, 323Ci, 325Ci, 325i, 325ix, 328Ci, 328i, 330Ci, 330i, or 330xi differential housing. If you have a custom limited-slip differential, you need this diff cover to protect your investment! 

During even short track sessions, the friction from the clutches and gears in your limited-slip differential heat up the fluid to a critical level - this is the reason you'll often see fluid seeping out of the vent hole after hard use. The massive cooling fins on this cover help to keep temperatures under control, which will increase differential life and avoid costly failure.

Kit Contents:
  • Genuine BMW Finned Differential Cover
  • Genuine BMW Differential Drain/Fill Plugs (2)
  • OEM Reinzosil Sealing Compound
  • Red Line 75W90 Differential Fluid (2)

*This kit includes 1 extended M10x60 mounting bolt, which is required when converting to the finned differential cover.  For the other 7 mounting holes, your factory bolts can be reused safely.
