When I went to change the oil in my 2005 Impreza Outback Sport I expected it to have the same filter as my Legacy Outback, instead it had a small black filter that, I am told, is also used on the WRX models. Anyway, it is recessed up inside and there is no room to get a strap-type wrench on it. I ended up changing the oil only because I couldn't get the filter off. I have tried every auto parts store around and every Subaru dealer, but I can't find a cup-type wrench (like a big socket wrench) to fit this filter. I would prefer not to get the type of filter wrench that destroys the filter getting it off. Also, I want the cup-type so that I can get a little better grip when installing the filter (I know, you're not supposed to use a wrench to install the filter; I just want a better hand grip.) Does anyone know where I can get a wrench that fits this filter? Any other ideas? Thanks.
