AEM is da best...i just got a short ram intake recently...ders one in ebay for only 130 bucks and free shipping (dats where i bought mine)...all original parts, including clamps (it will say aem on the clamps), has instructions... NOW, if you have a 2003+ civic, dx,lx or ex, the engine has a bigger throttle body, wit the aem intake it will make your engine scream, SERIOUSLY!!!! it scared the **** out of my friend...
