I did a cross reference with the AMSoil larger oil filter part # SDF-36 with the K&N parts line, and it looks like the larger K&N HP-1006 filter should fit the VX as well. The AMSoil SDF-36 filter fits the '96 Ford Probe (4 and 6cyl). Referencing that info with the K&N filters, and it comes up with the HP-1006 for both Probe 4 and 6cyls as well. In theory, if the SDF-36 fits the VX and '96 Probe, then the HP-1006 should fit as well.

It is just another larger oil filter option.
