"I was really surprised how easy and effect the AEM Cold Intake System installation was for my 2011 Scion XB. I can feel the extra horses and the sound gives this 2.4 a new personality. I'm not sure about my gas mileage, because its so hard to resist opening it up just to feel and hear the new system work. 5 stars AEM! joel" —Joel T from Hilo, HI bought an AEM Cold Air Intake System for a 2011 Scion xB.
