It is, but be advised this was a test on air filters for *one specific
application* which happens to have been a GM Duramax diesel engine. I'd
hesitate to generalize these AC-Delco results to a non-GM application,
only because I don't know the degree to which AC-Delco buys and reboxes
filters for non-GM applications. I'd have to scrutinize the construction
details and compare to other filter makes to see.

Pffft. "It's German, so it *MUST* be better!" (and variants of the same
fairy tale) is the only existing basis for such opinions.
