Unfortunately, Amsoil has not released air flow specs yet. The line of filters has just been released and test results are still in process. Sorry for the lack of data, but it should be available soon as more filters are out there and Amsoil gets further along with testing.
We are testing a few ourselves. I have sold a few, and we are testing them after replacing the 2790. I will post results.
