I'm a fluid power specialist so many of you don't know me. I'm not a big poster on forums. The company I work for makes filters and we are the largest supplier of aftermarket automotive fuel and oil filters (I'm not talking about spin-ons). I'm in process with some other companies to go this same route. This was geared more towards pro-stock cars making 1000's of horsepower so if the turbo let loose it would not send metal downstream to the motor. Would it see a benefit on regular cars possibly, but has there been any research for DD no. The biggest concern is restriction. There are already restrictors in line so you must be careful when putting another medium in place. A typical oil or fuel filters runs 40 micron Nominal (if your not sure what nominal and absolute filtration means visit [ www.noria.com ]) I won't get into the dynamics of filter medias and effiencies, but for this application yes you are correct in the wire elements. They are re-cleanable as long at you properly clean them and let them dry before installation. You might what to also consider engineering a bypass so if there is containmention it won't create pressure in the line and allow the oil to go back to the motor. If you would like to discuss this I would be happy to help in your indevor.
