Simple question: Purchased a new HD black filter todayfor my Street Glide:newsmile047:, and peeked in package of a chrome filter. The black one had a visable orange gasket inside (anti back flow?). The chrome filter appeared NOT to have the same thing. Main question is, are the filters the same except for the outter appearance? My "parts counter" human stated that when I asked, but something is fishy here. Any clarification would be appreciated.
