Thanks for posting. Good to know that this size seems to work fine in a 2001 Civic.
Actually when new, the Honda dealer didn't have the new 7317/14610 size yet and was using the older/larger Honda filter for several oil changes done at the dealer. I know it doesn't make very much difference but the sump is relatively small in the Civic and I feel any little extra oil capacity can't hurt.
I've used both sizes interchangeably though.
