This style of Cabin or Pollen filter was fitted to all Range Rover Sport (up to 2013) and Discovery 3 and Discovery 4 vehices up to the end of production. It will not fit the later Range Rover Sport L494 which was released in 2013.
Here at LR Centre we feel it is important to change your pollen filter every 12 months as a dirty, unchanged filter can sometimes be the cause of costly Air Con system problems.
