Good link, X5 in AK, thanks for this. I read this report some time ago, but had misplaced the link. Like the author, I am amazed that people buy into the marketing hype for 'low restriction' oiled foam filters. They are supposed to be filters, and any restriction is a byproduct of them filtering. If you want less restriction you should just take the filter out entirely, and run it until you need a new engine.
