ok here are the pics of the filter location for M35 (V35 too i guess)
this is after removing the glovebox, i assume most people can manage that so i didnt photograph it.
The first pic is the location of the filter. pretty easy.
on the left is the clip that opens the door (pic 2) to remove the filter.
when you put the new filter back in, be careful not to squash your filter. there are locator things that stick out of the door. the filter resides in the top half of the gap.
my old filter was squashed and didnt filter too well, it was also black as shit.
the 3rd pic is the part number of the filter. its very much available in australia.
