If ya bike's out of warranty ya don't have to worry about dealer excuses.
I run these units on two bikes, one has an oil cooler and the other doesn't.
After seeing the difference in oil temp on the non oil cooler bike I decided to run on on the other as well, I did notice a drop in oil temp.
(BTW, our max temps here this week range from 42 C to 46 C)
I'm happy with the particle size rating and more than happy that the units have magnets in them, you do get to see if there is anything trapped in the filters when you clean them.
I'm running 15 W 50 full synthetic oil and change it around the 4000 to 5000 kilometer mark, so, it's still pretty clean when done. Probably bad economy changing long life oil at short intervals, but that's what I like to do to keep things clean and insure there's nothing going on in the engine that shouldn't be.
It doesn't take a lot of effort to clean the filter, less in fact than going down to pick up a new OEM job. Although I USED to by them in six packs and always have at least two on the shelf.
And, I like the fact that they don't have bypass valves, who wants to dump unfiltered oil back through the engine when the oil is too cold,,,, or when the filter is too clogged to let oil through it ?
That's what oil pressure gauges are there to tell you.
Hopefully, if all is kept in good clean order and there are no gremlins attacking the engine the bypass thing should never happen.
I think that in the long run, it's all up to, and about how clean and safe the owner wants to be with his machine.
This type of filter is well suited to those that do their own maintenance and spanner work.
Cheers.
