Does anybody know of a source for the Aluminum screw in plugs on an intake manifold?
Thanks in advance,
John

I have a lot of brand new ones, various sizes, to fit a hex key. Can you measure the thread size/pitch and tell me the quantity you need?

Alex, the one in my intake manifold is seized in place and will be destroyed upon removal. it takes a 14MM hex key and seems to be 1 1/8" across outside thread to outside thread. Does this help at all?

I'm curious. Why remove it at all?

 

[Alex]

It will be a metric thread, of course, but I'll see what I can dig out.

Alex, thanks for the help.
Don, when I had some work done on the Manifold, I suppose in the cleaning of it the inner seat of the plug was a little too thin and subsequently it now has a few holes in it.
It was a spare manifold and quite likely was like this when I sent it out for the work. On my existing Manifold the plugs appear to be new, but again will not come out of the manifold itself. I do not want to destroy these plugs as they are now my only back-up.
