I am finding several numbers for 3.6L oil filters. 68079744AA, 68079744AB, 68079744AC. Some "AB" filters say for 2014+, some "AA" filters say 2014+. I ordered an "AA" from eBay and received a box marked "AB".

What's going on here and which is which?

Unfortunately I can't find a real Illustrated Parts Catalog for my 2016 JKUR to see in writing from jeep to what I need.

P.S. I hate dealers and would rather order online.

If it has the nipple on it. It is correct for the 3.6. No nipple.. 3.8

I don't remember the mopar part # off the top of my head

That is not entirely correct. The nipple on the filter got added to the 2014 model 3.6 engine I believe. The 2013 3.6 engine does not have that nipple on the filter.

The filter for the 2014 Wrangler is 68191349AB. The 2013 filter is 68079744AD.

Ok.. I got ya. But the OP is asking about the 16 model year. So the nipple it is. Part number on box should be MO-349

MO-349 seems to be on all boxes, no matter if it's "AA", "AB" or "AC" part numbers.

Mis-information is everywhere.

AA, AB, AC generally denote updated part numbers. I'm guessing it could be something as simple as a change to the packaging. Any of them will work and are considered OEM. As a rule, it's best to look for the most updated version.

14, 15, 16 oil filters are the same. If it's correct for a 14 it will fit a 16, whatever the part #. Open the box, see a nipple and you're good. dgreen's info. is correct, don't worry about AA,AB,AC etc. It's not misinformation, only updated numbers. Just do not install an oil filter for a 12 or 13 3.6 in your 16.

Or something as complex as a change to address a serious defect.

So to collect the good info I learned here:

2012-2013 JK's 3.6L use 68079744AA, 68079744AB, or 68079744AC filters (box model MO-744).

2014-2016 JK's 3.6L use 68191349AA, or 68191349AB filters (box model MO-349).

High letters (AA, AB, AC) designate changes to the base filter design, superseding or replacing the earlier letters.

So for my 2016 I buy a box of 68191349AB filters so I can change oil myself. What happens if another design change comes along (68191349AC filter) to fix possible oil pressure problems? I wonder if the dealer will accept the old "AB" filters in exchange for the updated one. Doubtful.

We're talking about oil filters which in this case part # updates really aren't an issue. If Chrysler finds a defect, for example, and part #'s are changed they publish a Technical Service Bulletin and the old (defective) parts are pulled and no longer used. In this case, there's no need to not use an older part # since there have been no design changes. Early parts (oil filters) are used until stock is depleted. It's not an issue.

This is why I only buy one oil filter at a time at my local dealer ($7.00). If Fca makes an improvement to the filter, I don't want to be stuck with a case full of oil filters.
For example, there is a newer, improved oem air filter for the 3.6 that came out a year or two ago...

Hmm, that's first I've heard of the air filter design changing, can you elaborate?

I bought an -AB from Amazon earlier this year... now they are telling me that part doesn't fit my 2015 Wrangler, LOL
Go with the Mopar number, not the Amazon fit guide. Amazon is wrong on many occasions. The "B" just means this is the second iteration of that part number. It will still fit your 2015 JK just fine.
