Replacement Procedure

  1. Open the bonnet, using the screwdriver, remove the 2 x screws at the MAF (1) and the 6 x screws on the Air Filter Housing (2)
  2. Inspect old filter (if desired, to see condition)
  3. Replace filter with new one and record mileage it was replaced on the pink/orange surround with a marker for future reference
  4. Replace the cover and screws on the cover (swearing optional when you drop one down the engine bay) :o(

I replaced my filter at 54466 miles on the car. I don't do much city driving but it does clog up.

The slightest bits of dirt clogging up the filter can affect the consumption of fuel on the vehicle

I realise this guide is completely basic but not everyone feels confident around car mechanics. This job takes less than 5 mins to do and can be done by a complete novice with cars. Perfect for developing confidence in maintenance of your vehicle
