Well.....this weekend I replaced the cabin air filter on my 2005 S40 2.4i. I can honestly say it was one of the more difficult things I have done to my car due to the lack of room to manuver & the @#$%^ lock nuts that hold the gas pedal on.
The most important piece of advice I can give you is to lay a blanket or a small pillow on the driver seat rail base (door side) so it doesn't dig into your ribs. It still hurts after 2 days.
I also recommend replacing the lock nuts with non-lock nuts. Getting to the top 2 lock nuts & putting them back on was difficult.
Getting the filter door on/off was not too bad.
Getting the filter in/out also not too bad. Filter had never been replaced & was full of junk/no air flow at all.
I replaced with a carbon version from IPD. BIG difference in air quality noticed on first drive post install.
It's a worth while job but plan on 70-90 min of tedious difficulty & if you're over 40 like me plan on a couple of days of a sore back.
Oh, I was lucky. I didn't drop one single thing like I usually do. Dropping a nut or extension could make this a very long job.
