For a street car and the RPM range of the motor, I don't think the physical size of the filter matters. I doubt if the oil passages, sump, & pick-up tubes were redesigned in the later ZETECS. My son has a ZETEC in his 99 ZX2 and it uses a FL-2005. The filter in my 2.5 Probe GT is 1/2 the size of the FL-2005 (FL-842). Don't sweat the size, just change em' every 3000 miles.
