Recently while I was at Wal Mart, I looked at the PH line of fram filters to see if any had the new silicone ADBV. The PH10060 had one, but I did notice the holes in the center tube seemed small, smaller than I remember seeing on Frams. The TG and XG 10060 were the same, small holes. Would this cause a flow problem? I looked at a few different Fram filters and the holes were all small, also.
