ca lambda thread size

[northerner]

Anyone know the thread size in the elbow ?

M18 rings a bell, pretty sure its the same as a spark plug

edit:-
have been known to talk cobblers of course , so will see if i can find the thread tap i bought to make a lambda boss

IIRC theres only 2 types of lamba sensors, and i think the det uses thin narrowband ones. tbh dont bother with it, its a waste of time and money.

Plug it up and fit a wideband sensor if you want to know your mix ratio

I'm going to be running a pre lambda ecu so was wondering what thread to block the hole up. I'll try a spark plug for now instead of welding it incase I get a wide band later
