Default A.I.R. Plug Size
I want to eliminate the AIR setup to unclutter the engine compartment but am having a hard time finding the correct side plug to screw into the exhaust manifold.

Does anyone know what size it is?


Thanks,

Jake

I used an oil drain plug. IIRC, a 22mm drain plug should work.

What year car did you use the drain plug on?

The plug on my oil pan is a lot smaller in diameter than the hole in the top of the exhaust manifold of my 96.

Thanks for that info. I'll try using one of my 22mm sockets to see how close it comes to the size in the manifold.

Saturday I hit two Dodge dealerships and bought two plugs.

They screwed in without a hitch, so that's one more thing completed so I can finally fire this thing up.

I really appreciate you guys pointing me in the right direction on those plugs: THANKS
