I recently installed a short ram CAI on my 97ex coupe, and there are 2 holes that are facing the valve cover.One hole protrudes out and another is indented. On the indented hole I inserted the hose from the valve cover, and the other I still have the plastic piece covering, it seems to be useless. What is the hole for?????? I posted the question a couple of weeks ago and got no response Any help would be appreciated Thanks!!!

 

theres a censor that should plug into the hole thats flush with the intake and the hole that protrudes out is the one where the hose goes ..

I have the sensor hookes up to the intake and the breather hookes up to the hole thats flush and another protruding hole. A total of 3 holes two are used
