An air filter (10) is provided by a housing (12) having an air inlet (26) and an air outlet (28), a main filter element (30) in the housing, a plastic outlet tube (44) having a sidewall (60) with a pressure tap opening (62) therethrough, a metal fitting (68) in the pressure tap opening and affixed to the plastic outlet tube, for receiving a pressure sensor connector (70), and an auxiliary filter element (74, 90) in the pressure tap opening (62) and affixed to the plastic outlet tube (44) and unaffixed to the metal fitting (68) such that the auxiliary filter element (74, 90) remains in the pressure tap opening (62) if the metal fitting (68) becomes dislodged from the plastic outlet tube (44) and falls out of the pressure tap opening (62), such that the auxiliary filter element (74, 90) continues to protect the clean side (38) of the main filter element (30) and eliminates a possible contaminating bypass thereto through the pressure tap opening (62).
