dude, do this- put some tinfoil over the part of your exhaust that is under the filter when you take it off. that way, if you spill, you can just unwrap the foil and it won't burn off your exhaust. i use to have your problem after changes, but no more.
oh yeah, i have a '97 zetec, the manual states motorcraft FL-300. i have to go to a parts store to get this, wallyworld doesn't stock this. they only have the FL-1A and FL-200. the 200 will probably fit, but its not what the manual calls for, so i stick to what ford says to put on it. good luck
