What air cleaner assembly to use

Thanks everyone.
I was also looking at this site http://www.ramairbox.com/ and thinking of maybe running some plumbing to my hood scoops and see if I can draw fresh air in via them. Dont want to steal a pic from their website but if you look at the bottom of this page http://www.ramairbox.com/install.html they have a 69 Dart with the induction up front.
