Use this Toyota Highlander O2 sensor gasket instead, available at Toyota dealership or also at autoparts stores such as Auto Zone, Advance Auto Parts, etc.

Here is the current Toyota dealer parts#/stock#, for that gasket...89466-20020-83.

If you shop Autozone, Amazon, etc., its a "Dorman" brand part number ...Dorman 47021...


When installing this gasket, you will need to slightly elongate the holes that go over the studs/bolts...I use a slightly largerbolt to do this through those holes.

You will notice that this gasket has some metal affixed to both sides of the gasket...The side that has the most metal is what goes against the exhaust pipe itself...DO NOT use any gasket sealers with this gasket.
Thank You, Great Info! Will pick one up. John

@DAMIEN1307. Picked up the recommended exhaust gasket at the local Napa (Napa Part # 6001152). Also swapped to the NGK BR6HS plug. It had a Champion J8C in it when I got it. Ran better and alot smoother at cruise speed --20 or so. Now I think I may be hearing a knocking of some sort. Oh well
the parts are cheap. lol
Thanks for the help. John
