Correction needed to 30680. Bad part number. Did not fit when received. I had to go to dealer and order correct door cover. Will post updated PN when available. Do NOT order 30680 pn.This is an update to a very old 2005 but very useful thread. I have a 2005 Land Cruiser and it did not even have the door through which to place the filters. 2 years ago I had the famous drip problem on the passenger side so fixed it by replacing the 15 yr old gasket. Today I am removing the same cover to put in my new cover that allows the filters to be inserted. I ordered the new cover Toyota OEM PN 88891-60040 plus the pair of Denso filters PN 453-1001. One package includes both filters. Then after installing the new cover and inserting the 2 filters, I start looking for the cooler cover / cap that should snap on to seal the system. Hmmm. Found out that is another PN that must be ordered separately OEM PN 88891-30680 for about $12 on ebay. It will be in after I return from Cruise Moab 2022 so I tried duct tape to cover and seal the rectangular hole. The air pressure from the fan blows the tape off so I will have to wait for the cap piece to really get it right.
Moral of the story. If you have a drip and want to change the gasket, look to see if your cover has the filter slot. While you are at it, for the same labor, you can fix the drip, clean out the filter compartment, install a new cover plate OEM PN 88891-60040, cap OEM PN 88891-30680 and new Denso filters PN 453-1001 to completely retrofit filters. Now for the bonus round, you can double check the glove box courtesy light making sure the headlights/parking lights are on. It the bulb is out, then you already have everything disassembled to replace the burned out bulb too. #74 bulb type is supposed to work.
