Just for my own info, does the technical specs match on both filters? Eg: the flow rate, maximum PSI, bypass etc. ?
No, because one is oversize, so it's a bit longer. Just ribbing you, Stevie.
Yes, they're pretty much the same, at least for the Wix filters, and probably across the board. Nissan actually specs the longer filter for a few of their applications, notably the V8s and some of the 3.5 varieties, depending upon the install, and a bunch of other seemingly random applications.
I use the oversize on occasion, since it gives me a silicone ADBV with the Wix and is actually cheaper. The quick lubes give everyone the shorty because they want to consolidate inventory (I've never seen where the long one wouldn't fit) and only dealers and shops are allowed to go out of spec, not us lowly mortals. As I mentioned in the filter subforum, on these engines, Wix actually has four that will fit it, and I've tried them all with no problems. Wix changed the base plate, with the 51358 being the short one, 56356 being the long one, 51365 being the original short and 51356 being the original long.
