I recently did a motor swap and I want realtime data on my AFR. When I did the swap I put pace setter LT headers on my 5.0HO motor. They came with a bung pre welded in each collector. The RH side header has the factory O2 sensor installed in the bung and there is just a bolt in the LH side currently. When I buy the kit I'm going to put the new wideband sensor In the LH side bung. My question is, is the wideband sensor in the kit the same thread pitch and size as the factory O2 sensor. Because the factory O2 sensor fit perfectly in the pre welded bung on the RH side.

Here is the listing for the kit on summit:AEM Wideband UEGO Air/Fuel Ratio Gauge Kits 30-4110 - Free Shipping on Orders Over $99 at Summit Racing

 

I cannot say for certain if it is. My AFE wideband came with a bung I drilled and welded in place, But cant say if it is the same as a stock O2 sensor

 

most of those kits fit. o2 bungs are standardized. iirc, 9/16 x 18 thread?

 

Yes the wideband O2 will thread right into the header.
