| Hi,
I removed my cabin air filter about a month ago and have so far been unable to find anywhere that stocks replacements ... so I need to put it back in, but I can't figure out how it goes.
The way that makes sense due to the shape of the filter and the distance of the guide rails from the edge of the box is with the solid surface and protruding edge on the outside and the inside of the concertina inwards ... however that doesn't make sense because it appears the air flows from the center of the car outwards, therefore in this arrangement the "dirty" side of the filter is on the far side of the air flow!
Any ideas? Pics? |
