In my experience the Champion nipple has a larger thread diameter on the filter side (13/16 IIRC), so the Tempest's 3/4 x 3/4 was the "go to". The short threaded side screws into the adapter assembly without drama. I cant remember how much force it took, but I did think it was loose enough to require locktite as extra insurance from backing out at a filter change.
That's just going to end with a lot of people selling used K&N *Air* filters in the Classified section...
AHA! This might explain my situation... My -6 has always had a nipple installed in the engine, and the threads on it are 13/16". I assumed that someone must have stripped/munged the stock threads and re-threaded and installed a nipple for the next larger size. This makes me wonder if someone just happened to remove a Champion filter and somehow leave the nipple in the engine, and since then i've always had a 13/16" thread (and i've been buying the appropriate Champion/Tempest/etc. filters that have a 13/16" female thread on them since I bought the plane). In fact, I went out of my way to buy the K&N reusable filter that had a 13/16" female thread as well... Which i'll be removing at the next change...
K&N air filters are excellent at keeping stones, birds, leaves, and insects out of the engine. Anything much smaller than that will get through. Thankfully most of our time flying is in relatively clean air as soon as we get away from the surface. I agree that an air filter test will result in a lot of disappointment, but perhaps it will help us find a better way to filter the incoming air, considering the challenges of aviation (rain, snow, ice at altitude, and dust and bugs near the ground).That's just going to end with a lot of people selling used K&N *Air* filters in the Classified section...
Yep, odds are if you pull it out of the adapter you will find 3/4 on the adapter side. Swap it out with the straight Tempest nipple (or aftermarket) and you can join the party with the rest of us!

Or just buy the Wix 51258. It has the 13/16” female thread you need.
The Tempest nipple has a shoulder. Just tighten it snug, it can't fall out with the filter in place.
Lycoming has used at least two different oil filter adapters over the years. I have the same 13/16-16 thread on my Lycoming. IF I go though the parts catalog, there will be two different part numbers between the one you and I have verse the one that is now shipping on new engines. I use the 48103 filter for most of the last 26-years.AHA! This might explain my situation... My -6 has always had a nipple installed in the engine, and the threads on it are 13/16".

I use this magnetic plug from Anti Splat Aero. Thankfully I have not found anything on it yet.

My adapter houses a bypass so none is needed in the filter. This is the same as the Champion 48103 which is used with my adapter if you prefer TSO parts.
I think the magnet will only trap particles that come within a 1/6" or so. I personally don't see a benefit for it on the filter. On the drain plug, The particles would sink down and be capture by the plug, so a magnetic plug is probably a good idea.
They are straight, on the male and female threads of every Champion I have dissembled. I just checked the thread diameters on the possibility of thread class difference. The removed adapter has the same thread diameter measurements on both ends. 3/4-16 Both ends are equally easy to thread in the back side of the oil filter end plate. It appears that the shoulder is used to deform the first thread for a mechanical lock. I would want to replicate this locking if the adapters are reused, and personally, would only use the shoulder type adapter unless al alternate design was tested for equal removal torque.
