You can do a search (if you haven't already.) People have their own opinions on what is the best. Volant or Iceman seem to be the most likes around here for intakes (I don't have it but I'm happy with my AEM short ram). The Ford Racing shorty header is very good (I DO have that one.)
aem intakes are hit or miss on if your going to have problems with them. more likely in the long tube from what ive seen. if you do get the long tube go to www.myfordperformance.com and get the weathershield for it because its real easy to suck up water with that intake and the filter gets real dirty fast.
volant is the best IMO, short rams dont cut it for me but they get the job done if you arent lookin to get too hardcore about performance. the ice man is good but the panel filter wont cut it if you mod past I/H/E
