I'm trying to fabricate the adapter plate for the 4th gen IACV to work on my 00VI install. On the back of the IACV there is a cup sized piece held in place by three screws. Was that piece left on and you had to machine out a piece of the aluminum plate to make it fit or was that piece removed?

Also, would removing it have any affect on the vacuum?

Thanks.

 

that little cover plate comes off.

 

You can remove it.

 

mine is gone

 

thanks. Makes fabricating alot easier.
