This post is late, but better late than never-the-less.
In 2008 Toyota redesigned all the oil filters to be internal to the engine. Upon completing this engineering masterpiece a new filter socket was introduced. It is very stiff and fits only this size filter. To date, no aftermarket companies build this tool and Toyota is still the only one that has them. We have removed the filters using some brute force methods, but it leaves the housing scarred and could eventually leak oil from the damage or become impossible to turn.
Until at least 2010 I recommend taking your Highlander to the dealer for oil changes. Try calling around to a well known shop and ask if they have the correct size wrench. (Do not accept an answer of "I'm sure we do." This means they don't).
