Model Number: 601904-DEFOULER

J Style o2 sensor fitting.

  • The "J" shape allows the O2 sensor to be installed parallel to the exhaust pipe for better clearance.
  • M18 x 1.5 Thread. The sensor to be used with this unit should measure 18mm from thread tip to thread tip. Accepts all standard O2 sensors.
  • Stainless steel construction
  • Note: in mid 2021, Vibrant revised this defouler so it is shorter than the previous version. It is still a 90 degree defouler, and has the same threading on both sides, but just shorter in length.

      would a defouler be necessary for a downpipe with an angled bung? i really don't want to set of a cel (which im hoping an angled bung may be enough) but with the J shape i think it would go on kind of funny.

        Any oxygen sensor that screws in, should work with this. The only ones we have seen that wont work with this are the bolt on style older Toyota oxygen sensors.

        This is a universal part, as long as you have a threaded oxygen sensor bung like the one pictured on our site, this should work. The only ones we have seen that wont work with this are the bolt on style older Toyota oxygen sensors.
