Background and Goals
My '08 C2S currently has 58K miles and 4.5 yrs on the clock. It's that time of year again... the pollen report indicates a very high count for the next few days and during this time of year my wife's acquires a fiendish dependency on nasal stray. So amongst the various projects this weekend I also replaced the cabin air filter within our vehicles.
I consider this DIY project a level 1-2 out of 10. It's a simple task requiring only a few steps to perform properly. Here are some instructions and pics which may help others.
Tools Required:
- a pair of hands
Parts:
- Cabin Air Filter for ~$20: http://www.pelicanparts.com/cgi-bin/...C%20Each%20%20
Instructions for the 997.1: Look further down the thread for the 997.2 additive instructions from DGrayling
Remove the cover above the battery compartment within the frunk by turning the two plastic tabs. Then remove the side cover as well by lifting it up. Note that the thin plastic retainer strip running along the side is held down via Velcro tape.

Lift up the foam flap covering the cabin air filter assembly. Note the plastic retainer bracket at the center of the filter. Slide it to the left to remove. There is also a retention tab on the right side towards the rear of the filter. Flip that tab down. Now the filter can be removed.

The paper filter is now accessible and it is pliable so push it in the middle to loosen it from it's frame and lift it out. Note the inlet port/opening under the air filter chamber. This is a good time/opportunity to vacuum any debris out of that area.

Now install the new air filter noting the direction of airflow... arrow should point down. When the new filter is properly secured into it's frame you should not see the foam sealant liner at the bottom of the paper filter. The foam part of the paper filter should be hidden if the filter is pressed down far enough. Afterwards it's time to re-attach/re-install all the latches and panel parts in reverse of the above instructions.

An inspection of the old filter reveals that it does have some oak tree pollen seeds lodged in there. I recall that Porsche recommends a much longer period in between changes for the cabin air filter but I prefer to change it at least once every year even if I've only put 5-6K miles on the car... Especially as it's only $20/filter and makes my better half a happy camper in the passenger seat.
My '08 C2S currently has 58K miles and 4.5 yrs on the clock.

That's awesome D. Plugs are fun to do... well therapeutic for some of us gear heads. I just replaced them on my son's Tundra and my wife's Lexus along with brakes and rotors this weekend. Plug away...

The procedure for the 997.2 is nearly identical to the instructions above. The only real difference is that there is an aluminum bracket that needs to be removed prior to changing out the filter. A T30 driver is needed to remove the four screws. See photos below. There are a couple of wires that you need to work around, but it is not necessary to remove them.

thanks as always, USMC! i thought the cowl had to come off also but glad to see it's easier than that.
and i notice you mention "$20/filter"...my stealership wants $80! i even called back/asked them twice just to confirm they didn't make a mistake, as i had recently priced it out at pelican parts at $20. sure, i realize dealers are usually 20-50% higher than indys but seriously man, that's ridiculous.

Suncoast lists two genuine Porsche filters for both the 997.1 and 997.2 One is charcoal and the other paper at $69.95 and $41.15 respectively. The Porsche charcoal filter I purchased was manufactured my Mann, so I would bet USMC's $20 filter simply does not have the Porsche name stamped on it.

Great contribution for the 997.2 DGrayling. I'll edit the title line to include both 997's. BTW, I'm using the German made Mann charcoal filter from Pelican Parts... a great value at only $19.75.
