  • a.
    The filter is installed so that the arrow, on the end of the filter, is facing the rear of the vehicle and is pointed upward.
  • b.
    The microfilter sits on top of the two black plastic tabs, not behind them.
  • c.
    The ledge on the back side of the microfilter cover panel slides below the microfilter.
