HOW TO FIT AIR FILTER

A number of different air filter housings are used in different vehicles, varying in shape and size dependent on engine size and space constraints. Replacing an air filter is generally a straight-forward task, requiring nothing more than unfastening the clips on the housing, removing the air filter element, replacing it with a new one, and ensuring the housing is closed and sealed securely. However, certain vehicles, such as the VW Polo, have a plastic engine cover which needs to be negotiated. In these cases, the following steps should be followed:

  1. Remove the air breather pipe from the left-hand side of the engine cover.
  2. Remove the engine cover in one piece. It is held in place by a series of rubber housing clips, (see picture below) fitting over four engine mounts and the intake to the engine. Starting by gripping the back right corner, then moving on to the back left corner, followed by the front, ease the cover firmly upwards, thus removing the housing from the inlet to the engine injection system. (Note: this is best done when the engine is still warm).
  3. Turn the cover upside down and remove the ten air filter screws in the order that they are marked. (i.e.1-10)
  4. Lift off the unscrewed section and replace air filter.
  5. Replace the lid and re-tighten screws 1-10. Turn housing over for replacement.
  6. Replace the air breather pipe to the air filter housing.
  7. To make future air filter changes easier we suggest you apply a light smear/spray of silicone to all the rubber fitment grommets. Ensure top right-hand corner of the cover is placed centrally over the intake of the injection manifold, and push down to secure fitment. Do the same with the left-hand corner & then front, ensuring the engine mounting pegs enter the holes through the rubber housing clips.
