Below is a link to a disco3 pdf written by d3matt that shows the install procedure for the pollen air filter. Air flow is from the top down into the fan.

The filter being used in the pdf is what I call the good filter, the activated carbon one with the charcoal in between the filter elements, part number JKR500020; the cheaper no charcoal filter is part number JKR500010. I think the activated carbon filter is worth the extra money as while I do not notice it, others do. Riders have said the vehicle smells fresh inside. It took me a while to figure out that what the riders were noticing was that the air within was fresher, and hence there was a difference between inside and outside - kind of like after a rain. The carbon bit was removing smells etc as the filter cloth was removing dust.

A jpg in the pdf shows the little flap arrow pointing down and that is correct. It is tricky as the flap is such that one could have the filter oriented correctly and the flap such that the arrow is pointing up.

The purpose of the flap is to provide a tighter friction fit of the filter. Also the filter, once inserted, is to be tipped / pushed up so that you do not see the arrow. This is the trick, as otherwise air tends to bypass the filter.

With Land Rover, it seems that there is always a technique to getting it right. Also I write on the outside edge of mine with felt pen, the date of install and mileage.

The jpg's below are of the activated charcoal filter I recently removed. The filter was in service for about a year. The jpg on the left with the tree leafs is the top side; the right jpg shows the bottom side. Note the air flow arrow direction when the flap is tucked along the filter edge.

That sample sure looked dirty. Any thoughts on improvements of normal filtering with the charcoal filter, does it reduce skunk odor, etc. ?

You ask a good question. Now that you mention it, I have not smelled a skunk in the last few years since I purchased the 3, and fortunately have not run over a skunk yet either. I am certain that I would notice.

Maybe the charcoal does work; in fact I have not even smelled a packing plant either and some stock yards when one drives by in the spring, well I should have. As to how the charcoal filter is vs the normal filter, I do not know as all I have run is the charcoal one.

I will pay more attention to the smell question in the next while. I am going out into the country this weekend.

Yes, the filter I removed was it would appear, quite dirty, even the dry leaves still on it - that is one reason I took the picture. I think the filter works better than I assumed.

My wifes 4Motion Passat has about the same charcoal filter installed, and I would say it looks about the same after a years use as well. Since we have winter here about 7 months a year, the dirt dust etc is only from about 5 months, so if one lived in a paradise like Oz, well then maybe the filter should be changed every six months.

When i look at any Land rover i pay attention to the plenum finisher if the filter is not there i always consider the vehicle to be not well serviced/maintained.
I have over the years looked at plenty of P38s where the cabin filters are very hard to get out due to the build up of leaves and dirt. Plenty of owners are unaware that filters are even fitted to their vehicle.

Pollen filters (charcoal) are just over $40.

Fourx4 in Kotara sell complete filter kits for RRS/D3 for $165. Consists Oil, air, fuel and pollen filters and sump plug and gasket. Be aware - fuel filters changed with 07my.

My Indy doesn't change the pollen filter unless requested.
I think LR were charging over a ton . USD27 plus tax over the pond.
Typical , hey ?

I change my own pollen filter now, but the one time the dealer did it, the cost of the charcoal pollen filter was $61.25 plus taxes. Labour was buried with other service costs.

The cost via mail order for the charcoal seems to be now about $45 OEM, and for an aftermarket unit, $25
