| Post subject: | Exhaust Manifold Pipe Fitting Plug |
I am restoring a 1986 Dodge D150 with the 225 slant six engine. I purchased a NOS Chrysler 225 exhaust manifold. It has a pipe fitting hole on the right side of the heat riser that I believe is for an O2 sensor. My O2 sensor is further down the exhaust system. What kind of a plug do I need to plug this hole? Is it a 1/2 in NPT fitting or something else? |

Move your O2 sensor to the manifold; you'll have better driveability and economy that way. And put in a new one -- not a Bosch; use an NTK, they're the best -- while you're at it. You can leave the old O2 sensor in the lower location as an effective plug. |

IIRC O2 sensor thread is unique. There are companies out there that make plugs but you won't find one at a parts store... I would do as dan says and leave the old one in as a plug. He is also right about ntk vs bosch, you will find that same statement on many automotive forums from people in the know. |
