I had the same internal debate, and decided I'd rather have too many than not having one when it was needed. At just under $5/filter, and filters having a long shelf life, I mashed the Buy button.
It's my understanding Honda hasn't changed their filter fitment (maybe a part number and build, but all are compatible?) for many years. Their filters are the same for all Honda models except for the S2000, and there are other brands using this filter, also.
