Grille Cover / Radiator Muff for Land Rover Defenders

Control the flow of air into your Land Rover Defender radiator with a high-quality British-made radiator muff!


  • Attach to the front of the grille on your Land Rover Defender with cable ties using the rivet holes provided in the cover. Shown in the photos above.
  • No tools required.


  • Useful for when either off-roading or wading in deep water to help prevent water and mud entering the radiator and clogging it.
  • The radiator cover can also be used to control air-flow into your radiator and help the engine and therefore the interior heater warm up faster in cold, winter weather. The cover can be left closed to restrict air flow and then rolled up in the open position once the engine has reached optimum temperature.
