I need to seal up the secondary air injection ports on a 2003 4.6 engine. Does anyone know the thread pattern/size of the holes. It appears, as usual, it is some pain in the ass pattern as NPT stuff doesn't fit. I need to plug the holes ASAP to get the Disco back in action to help with a move. Can't quite figure out how to move tables and chairs on my motorcycle.
Thanks,
Evan

They are on the way. Just left the PO, they said 2 days. Sorry about the delay, it's been a busy summer.

What other changes are needed to remove SAI? and how much are those plugs? :)

You have to have a non SAI ECU. Other than that, I think you're good.

edit - not sure about the plug size. If you can bring on of the SAI pipes to lowes or something you could probably find something. At least I would think so.
