For the filter put on way too tight on Edwin, I just took it off today with a $12 strap wrench from Kragen. I had to get a big wrench and a little one in the $12 kit, but they worked OK. It was way too tight. Now the new one is on correctly. I would recommend a strap wrench and not the plastic one that fits over the end, as the strap one really fits well from friction and can't skip and slip.
