Oil filters

What oil filters are you running on your cars? Some individuals on another forum mentioned MANN as a good choice. Anyone tried them?

My three favorites are the Mobil 1 High Efficiency Oil Filters (~$9), the K&N Gold Oil filter (~$9), and the Pureoilater PureOne (~$5).

I've used Mann; they are a high quality German filter. AMSOIL filters are also very good but expensive.

Mann is the O.E. (original equipment) supplier for VW, Porsche, etc in Europe and provide middle of the road efficiency. I have worked as a product design engineer for 20 years for a filter manufacturer in the U.S. who is O.E. to VW/Porsche North America in addition to just about everyone; GM, AC, Ford, etc. Personally I use Bosch Premium or Super-Tech (WalMart believe it or not). The Mobil filters have too many pleats of media (paper) stuffed in them (for advertising reasons) and are quite (flow) restrictive. AC makes some super high efficiency filters with glass reinforced paper media that are great but I believe are a bit too efficient (i.e. restrictive through the oil pump). The Super-Tech filters at $2 or so are more than adequate for your applications! Actually, if you don't mind going to AutoZone, the STP line is middle of the road fine too.

Thanks guys. Since I change my oil/filter only twice a year I don't mind spending more for a very high quality filter. I figure it's cheap insurance, when I consider what the motor in my car is worth.
