I don’t believe brand matters much anymore, so many brands are cross licensed or made by one factory producing a bunch of different names, with specifications that are ever changing. What *may* matter is choosing something that’s not the lowest tier in any given brand; that will get you better anti drain back valves and bypass typically.
And what matters most is how often oil is changed. I’d rather do 5k intervals with Walmart oil than 10k with any of the boutique brands.

Fram XG3675 or Amsoil EAO64
Both *very* high quality synthetic filters w/ the long can. Wouldn't touch the rest of Fram's lineup with a 10ft pole, but their ultra synthetics are on point. And well.. Amsoil is Amsoil.
IMO, better filter > better oil. Even the best oil will do you no good if it has floating particulates and contaminants in it

Agree. I use Amsoil signature and matching filter.
With all my years in shops and all my own vehicles, including Harley's, I have used WIX quality with never a problem and will continue to do so. The application of your filter is the same as mine and I still use them but I like a little more oil capacity and use the WIX 51522XP that is slightly over 1" longer than the 51042XP. The other dimensions and specs are the exact same. Yes, they are hard to get though.
I use WIX as well. Either the 51042 or 52042XP, whichever is in stock. I talked with a guy at O'Reilly about a year ago about them not having the regular 51042 and he said it was a nationwide issue, so I shelled out the extra couple of bucks for the XP.
I used to use the AC Delco PF46 filters when I had oil changes done at the dealership and through my first couple of oil changes because I got them for next to nothing. Once they switched to the E cores, I went back to WIX.

If all else fails, you can use the NAPA Gold oil filter for a good quality WIX made filter.
I think you meant 51042xp, correct? No such number as 52042xp at the Wix site.

That filter is not avail in the usa either very strange they dont have any oil filters in stock for a 5.3.I know wix was bought out by another company awhile back.
I have a 51042XP for sale. First $200 takes it........
They have a case of 6 of the 51042XP for $72 at Amazon. None of either of my numbers at RA.
That’s correct. I got to typing too quickly

51042xp I found one on ebay for 16 bucks free shipping ordered.I have been doing a quiet test on oil pressure with different filters.Wix will be my last test-i have only tested 2 so far.Mobil 1 and royal purple.Mobil one gave a higher pressure reading and i thought that was interesting.This is 3-5k miles in between oil changes.

Used NAPA Gold on my 4.0L Jeep for several years. Seemed to do pretty well. I was satisfied. Some other brands of filters had flimsy back-flow valve "flappers", which can make a ticky sound almost like valve lifter tick. NAPA Golds filtered good and did not have any noise from the back-flow valves.
Quality WIX filter made for NAPA.

I'm surprised @swathdiver hasn't chimed in here yet. I believe he's done some "oil filter effects on oil pressure" tests a couple years back.

Well, the fellas here like Wix, a fine filter, but it is not the top dog.
Don’t leave us hanging!

Alright, this was done about 2018 or 2019:
I have personally used the PF63E, the M1-212A and the HP2011 on my truck. The Mobil One filter dropped my oil pressure about 2-3 psi compared with the other two. From the 1980s through the 2000s our family used FRAM filters without issue, even when we were broke and had to reset the OLM a few times. I used ACDelco filters in my muscle cars back in the day. Probably going to buy a case of PF63s for the Sierra since it goes through oil changes every two months. The K&Ns are probably the most expensive, they are about $15 each right now. The PF63s are $8-9 each.
Did the oil filter threads change with the GMT-900 models? My '04 filter has SAE threads.
