Anyone know?

Apparently its the same as a spark plug for the Pinto engine, hence the reason why there's one stuck in my downpipe

(just to blank off the hole mind

)

The reason I ask is that I'm getting an adapter made so that my EGT probe (1/8 NPT apparently) will fit in place of the Lambda sensor (currently located in the exhaust manifold - soon to be moved to the downpipe - replacing that sparkplug).

If anyone wants one of these adapters let me know.

Thanks

Justin

I'd thought of that, but its not coming out of the downpipe till I get the adapter made!

Best find a Pinto sparkplug from a breakers I suppose....

Instead of getting a bung made, it is the same thread as the oil gallery bungs on the engine, just buy one of these and bung up the old hole in the manifold.

I will try and get you a part number if i remember when i am at work tommorrow.
