Hello,

 

I’ve been looking around and can’t seem to find the answer, I’m looking for the right size plug/caps of the intake manifold for smog

 

Thanks

The key to your search is summed up in four letters:

BSPT

and I suppose some numbers and symbols.....    1/8, 1/4 3/8 and maybe 1/2

I bought American standard size brass and forced it in. Not much forcing though, they were real close already.

Bruce from ztherapy has that info in a thread on here somewhere. Let me look around...

Google "240z balance tube plugs".

Or just take the ones off you want to replace to a hardware store.

Thanks that helped, didn’t know what they called it. Would you recommend putting some teflon tape?
