I just got finished with this mod... well almost.
Several months ago, I purchased online what I believed was the right filter. I then attempted the installation and realized it was the wrong filter. I now have the right filter on order. That said, I think I should add a few notes.
First, this DIY is well written. It only took me about 15 minutes for the entire process. Most of the time was fidgeting with the cigarette wiring. PITA. I attached some pics so that it may help another member. All I can say is that I still haven't figured out a simple, fast way to unclip/reclip the connection. Aside from that, this DIY is an easy process saved me a lot of money. My car required service D which includes services 1,3, and 5. I asked the dealership to not perform service 5 which is the combi filter replacement. Without that done, service D cost a total of $204. For the heck of it, I asked the dealership's parts department the cost of the filter. $112! + installation. In total, I wouldn't have been surprised if the D service cost over $400. Well, not for me.
Anyways, thanks for the DIY and I hope the pics help.
