This new muff is claimed to be easy to fit - it takes between 15 to 30 minutes, we're told - and still allows the Green Oval to remain proudly on display!

It can be used open, which offers some restriction to sirflow; or it can be fully closed so the engine can warm up quicker. If you have an intercooler, open it up as soon as the engine is warm or performance will be affected. The muff can also be used as a wading blanket when off-roading to help prevent muddy water from splashing on to the radiator and blocking the airflow.

It fits all Ninety, One Ten and Defender models with the standard grille, including those with air conditioning.
