No, I don't have a flow testing setup in my garage. (Nor a dyno, alas.) Now how much would one of those cost? And how much time would I have to spend setting up a test?
As for how I know they need to be changed, I think the manufacturer's recommended interval is a good clue. Or I could just drive until they get black with dust & crud...

Also - If you can only find your filters at the dealer, you're not looking hard enough.

Plus shipping, if you order on-line. They don't (or didn't) have them at the local parts store.
