This is the URL for WIX Filter Corporation:
WIX Filters : Filter Look-Up
Here's Fram's site:
Honeywell Consumer Products Group
and
Purolator's:
Purolator Auto Oil & Air Filters
A lot of guys don't like Fram, so we won't get into that discussion here

, but their site does offer a valuable feature. Enter the competitor's filter number (the LF3692 lube filter, in this case) into the search feature at their site, then click on their part number (PH6607) when it pops up. It'll list dimensions and pertinent data, various applications (there are very,
very few single application filters out there), and below that - competitor's part numbers, so you can cross-reference to other mfr's. A very handy feature.
The funny thing is that my 2320 and the 2520 have the same engine (IIRC) - The oil filter they have for the 2520 is wider and a tad longer than the filter for my 2320 - it does have the same threads/gasket dimensions though..
thatguy - The equivalent shorter/skinnier filter is probably the WIX 51365/NAPA 1365, and the longer/fatter one is most likely a 51334/1334. I got into that in my 'confusion' thread,
http://www.tractorbynet.com/forums/oil-fuel-lubricants/134140-oil-filter-confusion.html I know they'll all work, because they've been used on 755's, my Gator and X595 and even the 955, whose OEM filter actually crossed to a WIX 51064/NAPA 1064.
If you really have some time to spend, enter the 51334 number at Fram's site, then check out all the cross-references to other mfr's. Man, quite a selection..
