So i ordered one from ford hopefully its thick enough for the job at hand. The one i currently have is 3/8 and i need 1/2 at minimum. I will update when i get mine in case anyone needs to know since no one i contacted actually had one in stock ,all of them are drop shipping and could not tell me.

If you’re looking to drill and tap for a nitrous nozzle, it’s probably too thin. N2O nozzles are 1/16 tapered tap and drilled with a D drill bit

What i have found so far is it could be 1/2 inch which is plenty, i am drilling to put meth it i 1/8 npt and uses an R tap or 21/64

So as promised i am providing an update about this spacer . Here are the dimension and it looks like its going to be the perfect way to mount my meth. Right now i have it spraying in my inlet before the TB but this will add another nozzle after the throttle body.

The front of the TB is 90 mm as advertised and tapers down to 86mm at the back and the front has an oring receiver groove. It is 19mm thick 3/4 of an inch . comes with bolts and an o ring. Hope this helps someone else along the way.

Given crappy fuel in my area and expensive i added an AEM meth kit and can run 91 octane spraying 1000cc of water/meth and not pull timing. I will be increasing the meth with another nozzle.
