OK I have a 2002 Ram 1500 Quad with the 4.7. I have seen the h.o. intake advetised, and it says it won't help a 2003 or higher, obviously because it is already at least that efficient. So I have two questions, my first question is if I get ahold of say a 2004 4.7 intake plenum, would that be the same or better than the h.o. intake plenum, my second is, will it fit on my 2002 4.7 (with out major modification)?
