Should be plenty of used hoses on this site from the guys that upgraded to the Afastcar radiator hoses.
http://www.pilotodyssey.com/PO/viewtopic.php?f=4&t=7449Just make sure to have anybody wanting to sell you a set to inspect them real close before shipping so their is no disappointments, 99% of the Pilot radiator hoses I have had my hands on were perfect and I would have no problem buying them but I have seen a few that had nicks and cuts on them and a few that were oil soaked and swelled up I would avoid these.
A quick hand wash in the sink with hot water and dish soap should clean them up so they can be inspected.
New batch of after market hoses.
