So I was thinking, which my wife wishes I would do less of, and I was thinking.....
Wouldn't a new air filter actually let more junk through? Obviously a dirty one restricts air flow below desired amounts. But for let's say oil analysis, isn't it possible that a brand new air filter could result in oddly higher silica numbers on a used oil analysis?
So. There must be a ' sweet spot' in the life cycle of an air filter?
