Yes napa has a shorter one, I used a 1515 on my Ford 302 in my hot rod, it was too long and I had to cut it out after installing the engine with filter ON. NAPA had a shorter version.

NAPA 1515 Gold oil filter

Occording to this YouTube video of the disection of a Napa Gold 1515 filter, it has the bypass.

Is it possible that the bypass function of the Napa is set to activate at a different pressure than the aviation brand? Do aircraft engines operate at a different oil pressure than the cars/trucks that the Napa 1515 is made for?
If the bypass function is in play much of the time for whatever reason, it is not filtering, and will be very nice and clean on final inspection.

From all the research I've read I wouldn't use much of anything from Champion any more. Their quality control has gone down hill and designs have been surpassed. Even the fellow that runs the division that handles Slick and plugs was not happy with how little the big shots care about this area of their business.

WIX 51258 (or NAPA Gold 1258) filter exchange for CH48103 ??
Weasel,
I believe the NAPA Gold 1258 is equivalent to the WIX 51258 (and I suspect manufactured by WIX). Has anyone tried either of these alternatives ?
Looks like except for burst strength rating of 345 psi vs Champion at 400psi (whether or not this is material is discussed elsewhere) the WIX 51258 meets the available specs for the Champion CH48103 (which also does not have an integral bypass valve, see https://www.championaerospace.com/products/oil-filters where it is clarified that the integral bypass valve is only included in the 108 and 109 Champion filters).
I am planning to try the WIX 51258 on my 0-320 E2D (which has a spin on filter adapter installed - it is the Lycoming part I believe - and takes the 48103 Champion or its Tempest equivalent).
Anyone with previous real world experience -- please report!
Some data:
WIX 51258 Spec http://www.wixfilters.com/Lookup/PartDetails.aspx?Part=13350
Champion "specs" http://www.championaerospace.com/assets/AV6-R-Aug2014.pdf (see pages 19-26). Other than a reference to meeting or exceeding SAE ARP 1400B, Champion doesn't provide much in terms of quantified specs. Anyone have a copy of the SAE standard ?
And some photos (first try, fingers crossed!):
Thanks,
Peter

Bob,
The WIX 51258 is 13/16?-16 female thread. The WIX51515 (n?e NAPA Gold 1515) is 3/4?-16 thread. The larger thread is needed to replace the CH48103 (without using an adapting nipple).
If I read the specs correctly also:
1. The 51515 has an integral bypass valve spec?d at 8-11 psi. The 51258 has NONE.
2. The 51258 is about 3/4? shorter than the 51515.

NAPA 1515 filter gasket Blew
My experience, I have used the NAPA filter since the engine was overhauled 45 hr ago. I installed 3 filters and blew out the filter gaskets fortunately all during ground ops. They were not cold starts, I preheat ( sump heater) any temp below 40F. I have an IO-320 using an Airwolf Lyc-10 filter adaptor for a remote filter installation. Talked to many Pros to help troubleshoot the problem. Airwolf said DO NOT run without Filter bypass valve. Not sure if the 1515 has one. The A/C Is grounded until I can find the cause of very high oil pressure. Removed the oil pressure valve, Lyc-10, checked torque on filter, all oil lines for inspection. Cut open filter, no signs of over pressure. In flight oil press high 80s, will turn this down 3 turns. Plan on installing a Casper Lab CL 1000 using a AA48108.

2024 update - according to this video, and some of the comments, not all NAPA filters are still being made by Wix (which is now owned by Mann).
It's a shame we don't have a cartridge filter housing for our engines, which makes inspection of the filters both before and after use much easier. Perhaps a biz opportunity for one of you scrappy entrepreneurs.

I've been hand tightening oil filters for 50yrs, never had a problem. If you lubricate the seal it's very obvious when it's tightened just right. Not against safety wire, it's always good practice

Just checked my supply of NAPA gold 1647 filters and they are indeed stamped “made in USA” and still a Mann product. Just bought these a few months ago during the annual 75% off filter sale.
Back in the "great oil filter shortage" of 2021, I needed to do an oil change and bought the Napa 1515 filter, an oil filter nipple, and a hose clamp for safetying. I ended up not using it after Aircraft Spruce got my original order of Tempest filters fulfilled.
I got the "nipple" adapter from Amazon for a couple of bucks. I tried and tried to remove one from a Tempest 48110 filter to no avail.
You can see that the 1515 filter is slightly longer than the Tempest.
It does just barely fit away from the firewall.
Anyway, I still haven't used the Napa filter, but it looks like it is an option for you that isn't almost $40!

Couple points: the nipple comes out of the Tempest easily once you saw a slit into the base to relieve the swage. And the 1068 filter is essentially a “shorty” 1515.
Is there a good reason to use the NAPA filter other than the cost savings? Since I must burn about $1200 worth of fuel before each oil change I don't see a $20 more expensive filter making a huge dent on the big scale. On the other hand little things do add up. This is a tough one.. 
After all the destruction I have seen caused by K&N air filters, it goes against my conscience to say anything positive about their products, but the K&N HP oil filter burst spec is 550 psi. If I remember correctly, that's 50 psi less than the Champion or the Tempest. The Napa 1515 is 290 psi.
Has anyone ever heard of a NAPA 1515 or similar burst?... Like when some folks race an engine during a cold start? That's ugly and a good way to pop one!
An earlier post discussed filter material found in an oil passage. Two times I have seen this in automotive engines where debris that looked like filter material was in an oil passage to an oil control solenoid. Where did it come from?
I'm willing to bet debris probably fell into the filter when it was made or handled, and the installer was just careless and didn't inspect the center port for debris. I have no doubt many engines are lost this way. In most cases, you will never know if this was the cause of failure. By the time the engine quits, the bearings have been so hot, and the destruction is so severe that there is no evidence left.
That said, I always do the oil changes on everything I own!

This is exactly how I feel too. Verdict still out in my head.I don't see a $20 more expensive filter making a huge dent on the big scale. On the other hand little things do add up. This is a tough one..
Details? There are a LOT of them being used in these aircraft........

Availability at a moments notice is another. It’s nice to be able to run down to the local auto parts store and grab a few whenever you want. That concept should resonate with those who are still suffering PTSD from the recent “great filter shortage”.

Justified or not, the K&N products have LONG been known to pass a lot of dirt. Any hard core dirt bike or off road car that uses a K&N filter by itself (without a pre filter) will show a lot of dirt in the induction tract downstream of the filter. It catches the rocks, but that’s about it. That said, the environment of an off road car is quite different than our airplanes so the filter capability is less critical.
I was talking about air filters for automotive use. Just wanted to give a heads up for those running K&N's in their car/truck.
Planes operate in a completely different environment. I use a K&N in my RV6, but I wouldn't if it was operating in a dusty environment.
