There have been some reports on I8MUD board about the hairs/synthetic fibers coming off the vaunted toyota 90915-20004 synthetic medium filter and getting mixed with the engine oil. I'm coming to conclusion that you can't really go wrong with good old cellulose in a quality constructed filter.
Great looking filter altogether though!
If a "hair" came off, where would it go? The DP would just push it into the media anyway. I have nothing against a good cellulose filter, but they don't have any advantage (other than price) over an all synthetic media filter such as an Ultra, RP, Donaldson, Stratapore, etc.
