Champion vs Tempest oil filters for IO360-A1A

[Yourpilotincommand]

I have an IO360-A1A. During my last annual my mechanic used a Tempest this time around. I later discovered this. I’d rather ask for general opinions here on these oil filters. Thanks

Tempest are great.   I've been using them exclusively for years.  They have the pre-lubed gasket, which is nice, but are generally very good filters.

If you really want to go down a rabbit hole, Van's Air Force users bought several filters and sent them to a lab to see which one is the "best".

I use Tempest, but the reality is very few filters are installed long enough to make a difference as a result of their individual design advantages.

So what was the result?

I’ve done a little looking myself and from memory the Champion filters a little finer or claims to.

I don’t use Champion anything myself, I don’t think it’s worth the price
