We've gotten a couple shipments of the 15400-PLM-A01 (http://www.HandA-Accessories.com/15400-PLM-A01.html) oil filters in from Honda so they are currently available online:

as long as it says that part number in the description that is what we will ship. (once they are gone we will remove the 15400-PLM-A01 part# from the description)
