O2 thread pitch and size????

[155///MPH]

Does anyone know? The replacement set of downpipes I picked up has the first two or three threads buggered up.

Thanks,

i believe it is like 14 or 16 x1.5.

[155///MPH]

18 1.5 pitch

if you're looking to plug a o2 bung, get a toyota 22re oil drain plug (thread pitch=18-1.5) from napa or somewhere, can't be more than a buck or two.

I know this is an old post.

for future reference:

the 02 sensor is the same thread as an American spark plug. You can buy "thread chasers" anywhere.

in an emergency, buy a 99 cent spark plug and cut a groove in it to chase the threads.
