I use OEM oil filters, Honda uses them, they are easy to find, including, non Honda service and repair shops and I know what I am getting. Once again, the only serious issue I've ever heard of was from many K&N oil filters that have very suddenly "dumped" oil all over the road that the rear tire rolls right over with potential catastrophic results for the rider. If not catastrophic results, then wherever it happens, there you are. The sudden dumping is due to the faulty welded nut on the end of the filter. VFRWORLD has good pictures of it with results on the road. Seeing is believing.
