Can't find the weld-on bungs anywhere. An exhaust shop around here has em, but for $30...---- THAT!

 

If you're looking for a quick and dirty o2 bung, goto any auto parts store and get a set of Help! #42002 Spark Plug Non Foulers. They're 18mm which is the same as almost all o2 sensors. You get 2 of them for around $5. You do have to cut them in half though. Otherwise, any 18mm threaded Nut will work. I've seen quite a few turbo places on the web that sell 2 for $10.

Here is a one on ebay for around $7 shipped buy it now.

 

My cheap *** grinded the one out of my old DC sports header and welded it to my downpipe

 

4.99 HELP! spark plug non-fouler and a chop saw = $2.50 02 Bungs. Thanks1

Any Industrial parts company should carry an 18m x 1.5 nut & bolt as well...

 

I got a couple extra ones laying around you guys can have, let me know (3 to be exact)

 

Any hardware store that carries metric bolts will have it. I find that the smaller independant stores are better than the 'big' stores for weird ---- like metric.

 

carquest actually stock a slim bolt as an O2 sensor bung, only about $2 each. Works great. I had a bitch of a time finding these at industrial places, I struck out. 18mm is common but the thread pitch that you need for a sensor is an uncommon combination.
