I read there is a screw in the middle on a search i did, and someone said use a 1/4" drive torx, but they did not say what size!! I am taking it off to get at the lower intake manifold to replace it. I messed the other one up pretty bad. So, if someone would be so kind to relay this knowledge to me that would be awesome! anything I should know replacing this part? I know I have to take everything from the old one and put it on the newer one. It was 38.02 with warranty at pull a part

 

T40, either an extended bit ($$$), or use a grinder or file to remove a little of the plenum's casting flash down in there so a standard-length one will fit.
