the way i see it is ebay stuff you may think is shit.. but for the CAI (exclude V2).. piping is piping.. all your buying is the name: AEM or anything else, i mean if you want to spend 200+ on a CAI go right ahead.. but on ebay they have them for like $60-70 and its the same size piping and same bends.. i dont' get why the ebay intake brands are shit? on a 88-91 crx/civic ebay is way better b/c the AEM ones are like 2.5 inch diameter but on the ebay its 3 inch diameter.. more air than aem and i spent $30 on it with a filter, and i guarentee that i stayed the same for power from Ebay and AEM if not i gained more power cuz of the piping size maybe .1whp haha everything else ebay style is probably low quality but the intakes are fine for 3/4 the cost. just my experiences with ebay vs AEM.. its time for someone to bash it...
