The WIX filter will be fine also.
The Amsoil website lists the Mann filter for my 2003 Sienna also.
I have used WIX filters on my old '96 3.8L Ford Windstar for years......it has over 220K miles on it and the motor is still super clean inside.
The WIX website has a dealer locator on it.
If you have your heart set on the Pure One, the Purolator website,
www.pureoil.com has a listing of retailers also......including Canada.
You could then check the retailers (easy if they have a good website) and see if they carry the Pure One.
Also, the OEM Denso filter is well regarded.
In short, you have a lot of good choices for oil filters for your corrola.
It looks like the following filters come up for your 2007 Corola
WIX 51394
Pure One PL14476
Mann ML1009
These are the brands that you mention.....the order that I listed them is not any recommendation of 1 over the other.
One of our Amsoil Site sponsors may be able to comment on why Amsoil lists only Mann filters for some Toyota vehicles.
I read someplace that Amsoil was staying away from listing extended drain (over manufactures maximum mileage of 7500 miles) due to some of the "gelling" concerns with certain Toyota motors.
However, I have not seen the corrolla listed as having one of those motors.
