    Extender for Bolt-on Oxygen Sensors

    The pre-cat o2 sensor in my '92 Toyota Celica bolts on to the exhaust manifold rather than threading in (see picture below). I ceated a model of what I think would work for an extender for this type of sensor, which I know is in a lot of Toyotas and I think I also read somewhere that they are also in Saturns. Does anybody know what the cost would be to get something like this machined? Would it cost more than an EFIE?

    I have a 99 lexus that has an 02 sensor like the one you show ( its a toy you know). I found a relpacement sensor that has a bolts on adaptor that the 02 sensor serewes into. Advance Auto Parts has it. Beck/Arnley Oxygen Sensor Part Number 1568401 $152.51. With this setup you can screw in a spark plug antifouler.

    My car got the same miles with or wo HHO. Thinking of getting this part.

    Let me know if you try.

    just my 2 cents but sounds like you can by an efie cheaper and know it has been tested and could always sale it if it didn't work...
