zbane Posted April 14, 2009 Share #2 Posted April 14, 2009 As far as I know, there should be a plug in there. That hole was used in the casting process of the intake manifold, and there should be others like it under each of the runners (though I may be mistaken) Link to comment Share on other sites More sharing options...
