  • Q:

    I just placed part 234-9123 into my 2006 2.5L Subaru Outback, but I had trouble because Subaru seems to have added a white plastic fitment and a rubber gasket into their end of the connection. This part would not fit in until I removed them. QUESTION - This correct? Do I need to worry about moisture since the gasket is now removed? It would be helpful if you added this topic to the write up on this part so others know what to do.

      Hi there! This oxygen sensor shows to fit multiple Subarus and Saabs as well that may be why a part may need to be removed. Denso will be the OEM (original equipment manufacturer), when that gasket is removed you should put some of the grease in its place.
