if that fram filter is identical to the OE spec oil filter for the focus, then i guess my bad i don't know what i'm talking about. i've read and heard that fram is on the crappy end of the oil filter spectrum

personally i don't put aftermarket oil filters on my bike or car. i always picture japanese engineers to be really anal, detail oriented perfectionists so i trust whatever spec they have come up with and whatever supplier they have chosen to use.
