With the removal and re-installation of intakes, and due to external weather and under hood temperatures, the factory O ring on the MAF sensor will deteriorate over time. The FactionFab MAF Sensor Replacement O-Ring is a replacement for the factory O-ring. It has been designed to withstand temperatures from sub-zero to well over 200°F to provide you with years of worry-free use.


The Faction Fab O.E. Replacement O-Rings are a great way to replace your old, tired, and weathered units with high quality oil-resistant Buna-N units.


  • Direct replacement O rings for the factory MAF sensor

  • Subaru DOES NOT sell this O-ring separately

  • Manufactured out of oil-resistant Buna-N which has good chemical and high-temperature exposure resistance for a long service life
