Following up here: I ordered new filters from the BB dealer and when I installed them, they just didn't fit quite right, didn't have a perfect, intuitive fit and feel like the original filters. So I went round and round on the phone with the parts guys, measuring etc., they said they were the correct filters, that the filters had been redesigned so they might fit a little differently. Finally called enginaire and told them of the issues, that I had new replacement filters which didn't seem to fit correctly (was still using the original filters cuz even though the restriction indicator went off everyday, they fit right), they said we'll just send you new filters so you don't dust your engine. They sent them, they fit perfectly like the originals, the restriction indicator doesn't go off at all with them, life is good. Enginaire stepped up big time for their customer.
