Believe it or not... Advantages of oil bath air cleaner: will hold more dirt without clogging up, cleans the air better, less airflow restriction. Advantages of paper filter elements: less messy to change Advantage of foam filter elements: none that I can think of In addition, only the OE filter assembly can suck in cool air from the intake plenum, thus giving slightly more engine power. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
