I went to my Honda dealer to get an oil filter as I do my own oil changes. The parts guy looked up the 15400 PLM A01 and said Honda discontinued it and they don't sell it anymore. So he gave me the A02 filter. I've read on this forum that the A01 was a better filter than the A02. Do you guys recommend skipping the A02 and trying to buy an A01 off the internet?
