Begin rant:

The operative word is "silicone". The basic Fram is about the worst filter made. Even their website promotes their high mileage filter as 25 times better than their standard filter. The PH series doesn't use a silicone anti-drain back valve. At least get their Tough Guard model.

I went to the Napa gold website and they don't even mention the drain back valve. They do say it's a paper filter with synthetic fibers.

Go to the Bosch website and see their basic paper model has the silicone valve, 99.9% first pass efficiency. They are also playing the game with a extended range version. 

End rant.
