A 7317 will work. I've used them on my wife's 03 3.2TL (same engine) and now on her 09 Odyssey - about 150,000 km's worth of oil changes.
Rockauto.com lists it as the correct filter for all kinds of current model year and older honda V6's. In fact, before posting this, to make sure my memory holds true, I went to my garage and compared a fram 7317 to the factory blue Honda 0664 (which I bought at the Honda dealer last year - and which they tell me they put on almost everything) and they are outwardly identical apart from paint. I think you can be very confident in this regard, but to be sure, go to a site like Rockauto.com or fram.com and check the specific application. The other model you will see come up is the fatter and stubbier 3593, which I have also used. I believe they moved away from this fatty a number of years ago due to the location of the filter on the v6 cars. It's basically nestled above the center of the "A" in the lower passenger side A-Arm and for ease of access and removal, the skinnier 7317 works better.
Again the filter that your honda dealer will sell you for this application is blue honda 0664, which is externally identical to the 7317 (and is in fact made by Fram in Canada). Fram has been selling these for Honda v6's for many years.
Garden variety 5w-20 has done very well in our previous TL in used oil analysis and we get a significant amount of -32, and a ton of -20C. In florida you would have no worries even in the winter.
To reset the oil change light you toggle the ODO button until you get to the oil life %. Then hold it down for about 10 seconds until it flashes, then release briefly and hold it down another 3 -5 seconds and it should reset to 100%. This is how our 3.2TL worked and how our 09 Odyssey works as well.
Oil capacity is around 4.5L if I recall. 5 quarts will be enough to send him home with a little extra to keep in the trunk.
Another tip is that the filter can easily be removed by hand without jacking the car bay turning the steering wheel fully to the right and reaching into the passenger side A arm inthrough the front of the wheel well.
I hope this helps.
