ALL filters cause a change in pressure. Pressure == resistance to flow.
There are much worse things to run than the newer Toyota filters, but they're not very good and you can get much better for close to the same price. I don't remember how to tell the difference other than taking them apart. The old style used a varied density foam-like medium and the newer are paper. They haven't been available in North America for some time so unless it had a half inch of dust on the box when you picked it up it's unlikely it one of the famous ones... it's a shame too because they were supposed to be VERY good filters.
Anyone here uses a FRAM and I'm coming to get ya!
