Most guys ditch the huge plastic home plate, but we were making due with what we had, and we think having it there will make the smog demons go easier on us. We used the stock Caprice "home plate" and rubber 90-degree elbow. Most guys just put the Mass Air Flow sensor on that, but it was rubbing hard on our upper radiator hose. So we used the upper portion from an old AEM intake, the stock Caprice rubber MAF collar, the MAF itself, and then an AEM dry-flow filter. It is important to stay away from oiled filters if you have a MAF on your engine, as the delicate sensor element is sensitive to oil.
