Seal the intake manifold connection and dampen engine vibration with the MAHLE Engine Intake Manifold Isolator Grommet Set (GS33438). It installs as a direct-fit replacement for the listed applications, including the 1999-2003 FORD WINDSTAR, 2001-2003 FORD F-150, 2004 FORD FREESTAR and 2004 MERCURY MONTEREY. The isolator grommets cushion the intake manifold where it mounts, helping maintain a sealed path for metered air into the engine while limiting transmitted vibration.

  • Vibration isolation: the grommets cushion the intake manifold connection to help limit vibration and noise.
  • Metered-air seal: helps keep the intake sealed against unmetered air, guarding against vacuum leaks and a lean condition if worn grommets are the cause.
  • Service set: supplies the isolator grommets needed to reseal the connection during intake service.
  • MAHLE build: a MAHLE replacement set for the listed Ford and Mercury applications.
