Anyone ever rig an O2 sensor on a carbed y-pipe?


Recommended Posts

you said bung:lol:

 

Joel try Trade center salvage out passed the mall. I got them to sell me and EA81 Y pipe a few years ago.

There's only SPFI car in the all the junkyards in Junction! It's down offa S 5th... It's a 90 4x4 with a bad 3AT, but the y-pipe was rotted.

 

Aparently the guys there used to race a Hatch in Tough-Truck competitions! They got a kick outa the wagon.

 

Anyway, a local muffler shop said $35 to do the job. More than twice what I paid to have my diff welded, but not bad.

 

BTW, anyone know what the thread pitch is for our 02 sensors?

i'm looking to get a carbed y pipe from the marketplace forum from XNRG. with a welded in O2 bung will i be good to go on my MPFI XT? other than the O2 sensor the carbed vs. MPFI y pipes are identical?

It seems that way,at least for SPFI. A local muffler shop put in my bung for $15.

Almost all oxygen sensors have M18x1.5 threads.

 

So do 18mm spark plugs, actually. You can get 18mm "spark plug non-foulers" from the auto parts store that can be easily made into weld-on-able oxygen sensor bungs with a little cutting. They're basically little spark plug extension dealies:
