I went to buy some oil filters from my favorite internet supplier And it looks like the same filters I ordered 4 years ago are no longer available. At least they are no longer listed by the same part numbers. I like the Denso part # 150-1007 AKA A6000-116742, and now its listed as A6000-35265. It looks like the picture is the same so I went ahead and ordered all they had in stock. These were some of the filters that were the closest to the old OEM Nissan filters. I also ordered some filters made by FULL, anyone heard of them? They look like OEM filters as well, just white in color. So it looks like the aftermarket my be going the same way as Nissan, and stop making a lot of different filters. One fits all.
