The smog hose that was attatched to your stock intake attatches to it. If you bought a pre-cut shroud, don't zip tie it to the holes provided, it's a bad location IMO. If you stand directly in front of my car with the hood open and look through the crack, its cable tied directly to the right of the box, with the hose end facing up, so that the hose comes up, over, and down into whatever the hell that little thing is.
You're gonna love the results! Why people bother with the pain in the a$$ installation of the Vararam is beyond me. The car kicks @$$ on the highway, I go from 100-150mph like its nothing.
