Got a follow up call from Champion Labs today to make sure I was satisfied.
Mr. Bill Burch confirmed that the ST 2808 was identical in all function to the Honda OEM filter. The replacement filter, ST 3593A, was modified slightly so that it not only complied with Honda OEM specs, but certain Subaru specs as well. This was at the request of Walmart to reduce the variety of model numbers they had to carry (and save shelf space)
He reitereated that there had been NO quality problems with the 2808 filters and that I can use my remaining stockpile without fears. He stated that hundreds of thousands of this model number had been sold with high quality standards.
Overall, I'm impressed by the responsiveness of this Company. All I asked for was for them to respond to an internet rumor and I got immediate and thorough response. Very unusual.
