So...in the process of removing my stock downpipe to put in a zzp header/downpipe, my brother stripped the threads on my downstream O2 sensor. Unfortunately, it's hard to find any O2 sensor at 10pm...so i drove home sounding like a supercharged weedwacker (i STILL dont know how my new full exhaust sounds). I think i found a local store that has an O2 sensor for me. just in case that doesn't work out, i need a plan B. What is the size and thread pitch of the O2 bung? i need to know in case i need to just plug the hole for a day or two with a bolt or pipe plug. I THINK the bung is 18mm x 1.5...but i need to make sure...can anyone help?

BTW...if you think a catless dp sounds sexy...you should try any aftermarket downpipe with no rear O2...it's amazing!

 

your local dealership should have a few extra to buy

 

i know the threads are 18mm not sure what thread count is but 1.5 sounds ok, if you have any autozones, pepboys or advanced autosports they should have 02 sensors.

 

Drill + insert, dealership have these inserts

 

The thread is in fact an M18 x 1.5
I just got a bolt to plug up the wideband bung on my vibrant downpipe.. So I know that for sure.

 

sweet! thanks guys. i sent my brother out to get a universal O2 sensor...i could use a longer wire anyway...so it's no big deal. called the dealer, napa, autozone, advanced auto, and murrays, nobody had an OEM in stock...they all had to be ordered. i figured the universal was my best bet. if by some chance it doesn't work out...i now have verification on the thread pitch so i can at least plug it temporarily.
