I've got a Champion nipple, or should. Hopefully it's in there after the last annual.
I just wanted to make sure to go from Champion to Napa (if I go that route) I won't need anything outside of what I've already got.

Pretty strange - I just removed a Champion filter (CH48110-1) and extracted the threaded nipple. I just this minute measured the threads and both ends are 3/4 - 16 (shoulder in between). Outer thread diameter is the same too. It must have some thread specs different on the filter head to keep it tight.
Edit: No claims for any other filter part number.

There are two different thread sizes used on our Lycoming engines oil filters. Most new ones have 3/4"-16 but some old ones like my old narrow deck engine use 13/16"-16. I only have one filter adapter sitting in the shop to measure and it is 3/4"-16. I am making an assumption that there are some 13/16"-16 filter adapters floating around and would require a different nipple or a nipple that adapts from one size to another.
Looking up the NAPA 1515 filter it lists as a 3/4"-16 thread so would not work on an adapter that used the CH48103 or CH48104 long filter that is flying on my airplane. (Change CH to AA to convert from Champion to Tempest. Tempest may have a -2 after the part number also.)

OK, now it's coming back to me. I'm using a different NAPA filter and it needs the bigger (filter side) nipple that the Tempest features. Perhaps the NAPA 1515 is the same 3/4-16 that is on the Champ.

Filter
I use the Tempest filters and have had no issues. Purchase them in a 6 pack to decrease the cost a bit.
On my 4 I installed a Casper Labs 90 degree adapter to make it easier to change. I still had little room to the firewall. Casper told me to use HP1002 filters from K&N due to the smaller physical size (still lots of filter area inside). The guy at Casper told me they used to be a certified aviation filter before K&N bought them and are still made to the same spec with thicker wall can (for higher pressure), lockwire tabs and 1" nut. The checkvalve also works better than the Champion at keeping filtered stuff from being reintroduced into the oil. You can find them on Amazon to save even more. Worked fine for over 450 hrs and a dozen oil changes.

Bob's excellent investigation on NAPA filters made me a believer. But I needed a bit of accommodation for my particular installation, so I use the 1521, which is shorter but with all the other same specs. Oil analysis as stellar as it was prior to the shift from conventional aviation filters.
I cut the nipple out of a Tempest filter with the band saw (almost, twisted the last bit to free it) and installed it on the engine with some green loktite.
I do not safety wire it. I (still) put a dab of torque seal on it, visible from the open oil door on every pre-flight. 300 hours, no movement ever noted.

Ditto! I've been using NAPA 1068 (Wix 51068) for almost 5 years now with no complaints.

Hint........
If you use an oil filter that has no safety wire "tab", (such as used on the Rotax) you can still safety wire it by using a large hose clamp around the filter housing and wire to the adjusting bolt.

Many of these myths date back to 20s -30s.Auto oil filters ,even in NASCAR aren't.

I bought one of the HP1002 filters to try. I venture to guess it has about 1/4 the pleated media area of the 1515. Very small in comparison and unless physical room is an issue, there's no reason to use a small filter. The larger the filter, the lower the pressure drop across the filter.
