I am putting long tube headers on my 95 f150 5.0 302. I need to get a oxygen sensor bung installed in one header. what size threads is the bung? thanks!!

 

I wish I could tell you the answer, but I know I just took one down to Lowe's and bought a "jam" nut that fit. welded the nut to the exhaust and all was well.

The Jam nuts are thin, thus the sensor "sees" the exhaust.

We carry the O2 bosses. Easier to install than a nut, and possibly less expensive too.

 

thanks,but the exhaust is pretty much done,I found the size when I posted the same question on the forum for my truck when nobody answered here. I just bought a collector with the bung in it so I wouldn't have to drill into the header. for future search purposes,the thread size is 18mm
