hey, I ordered 5 of the "new" honda oil filters online, and the part numbers on all five of them were 15400-PLM-A01, which means that they are the Filtec-made filters, as stated on the packing slip. I got them here:

The site doesn't show the full part number, so I guess you'll have to email them and ask if you will get the A01 or A02s.

I have used the S2K filters on my H22 and my girls prelude as well with no problems I refuse to use honda/fram/honeywell on any of my motors.

I also order my filters from H&A accessories, and as was mentioned, I always put the part number A01 in the comments section and I have never had a problem. The two Honda dealerships only stock and sell the A02, which I will not use.
