Fram uses a glass blended cellulose media while Purolator uses plain cellulose which requires more media to achieve the same holding capacity. The Fram gets the job done with less media.
Also your prices don't match up with everything I see locally, what is your price source?

Yes sorry I thought I was in an oil filter thread!

Without knowing the efficiency or flow rate of the different media comparing pleat counts is useless.
I am pretty sure Fram knows what the oem filters need to be for flow, holding capacity and efficiency so they typically will meet or exceed those figures with whatever it takes.
