Using those filters at the turbos may introduce an even higher risk of turbo failure if the filters become excessivly clogged. You will need to stay on top of the filters with regular changes, but at what intervals??? Even oil sluge can clog those type of filters. Also, what type of flow rate will those filters allow??? If using turbo oil line filters I would want to use something better such as the ones aliaZ pointed out in Ash's post.
