I have used both styles and I think the double ADBV filters run smoother and quieter at start up, but that could just be a make me feel good thing and there is no real advantage.
Actually, the 400s did exist back then, alongside the 2005.
2002 Focus owners manual, first printing. Go to page 311.
Originally, the 2005 didn't exist when the Contour first came out, and the 400 was specified for the Contour/Mystique Zetec. But after awhile, people found the engine to be grumpy on startup, so Ford added the 2005 with the second ADBV.
I totally agree that the second ADBV is needed. My experience is with the M1-209 (a 400s cross), TG8316 (a 2005 cross, on the car now), and a 51315XP (a 2005 cross). Only the Wix works. When the TG8316 comes out, it will be replaced with another Wix XP (Napa Platinum 41315). I'd love to try the M1-211, but it's not sold in stores.
The Fram 8316 cans are short like the new 400s. The Wix 51315, Purolator 25230, and M1-211 are still the original (longer) length of the old 400s and 2005.
The funny thing is that the Fram 3600 is longer like the old Motorcrafts and the M1-209/Wix 51516/Purolator 20195 filters. Especially since Purolator makes the Motorcraft, but didn't shorten the aftermarket Purolator 20195
Thanks for the correction. I must have heard Ztec and remembered Focus in my head.
I have a M1-211 waiting to go on my Focus that I bought in a local store.
