I found this on a Honda part site, It pretty much shows the difference between Honda and Fram. I had read somewhere else that the filter # that ends in A01 is made by Filtech, and A02 is by Fram. I am just going to pick up a non oem filter to compare to, and if I don't use it on mne, we will save it for sister's Accord. http://www.handaaccessories.com/15400.jpg
