I believe the Fram filter for the Hayabusa is the PH-6018. I used this filter last year and this year on my SV-650 and had absolutely no problems. However, $10 for the Fram seems high; Auto Zone around here wants $6.99 for the PH-6018, and my Suzuki dealer charges $10 for the Suzuki filter, which I'm going to use exclusively, given the high state of tune for the Hayabusa. However, ten bucks for a filter is about my limit; more, and I'd be using the Fram.
I've never understood why a few people have such heartburn about using Fram oil filters. They are the largest selling brand of oil filter made by a company that has more patents for oil filters than anyone else in the business. Use their filters as their application catalogue call for, install them properly and change them when the manufacturer states, and you should have no problems. Fram stands behind their products, and they're easy to contact should you have a question or think that you might have a possible oil filter related problem.
Whatever your dealer says, the Magnusen-Moss (not sure about spelling) Act, to the best of my knowledge, precludes a dealer from denying warranty service based on a customer using a non-oem part of equal quality to the specified oem part.
