Looks like no one has posted on this yet, so here I go.I've been advised by a few people to install a filter on the aircon intake of my 2005 hilux vigo in order to prolong the life of the aircon components.Its a very simple mod. The shop charged me MYR75 (abt AUD25) for parts (filter & cover) and installation.The aircon intake is located behind the glove compartment. Just open the glove compartment and squeeze the sides where it contacts the dash and it pops out.Here's the intake. You'll have to cut out the opening. Its very thin plastic and looks like it was made to be easily cut out.
The filter
Insert filter into intake opening.
And snap in the cover.
Its a very simple mod. The catches for the cover are already built in. You just have to cut out the hole and buy the cover. Makes me wonder why they left it out in the first place.
