Finned Differential Oil Cooler Cover
for Ford Mustang 2015-23

Manufactured by FluiX | Part #NEM4004

The FluiX differential oil cooler cover replaces the factory differential cover on all 2015+ Mustang models. The FluiX cover has integrated cooling ribs, which increases the heat transfer by convection to the air passing through below the car. During normal driving, the FluiX cover reduces axle oil temperatures by about 7.5 C or 15 F. During spirited driving the rear axle temperatures are reduced by 15 C or 30 F.

The cover is casted out of highest quality aluminum alloy in Germany. All fittings, drain plugs and bungs are in the factory location. This means that the cover fits all 6th gen Mustang models without any custom work required.

This differential oil cooler cover comes with the option of the extra tapped 1/2"NPT Threaded Hole where an external oil cooler can be fitted to. We can also provide the required 1/2" NPT to dash fitting adapters as an option. Or External Differential Oil Cooler Kit. Please contact us for further details. 


  • Great for Track use (Circuit and Drag) keeping Differential Oil Temps under control.  2018+ Mustangs with factory diff temp sensor can trigger limp mode if the differential gets too hot.
  • Designed and built in Germany

Vehicle Application(s):

  • Ford Mustang S550 - 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023
