"This thing is so easy to install and i love the sound it make on WOT, its not as loud as the intake on my 07 Si but still sounds great. I had no problems getting on on it took me about 30 minutes and only required just a few tools. Would recommend AEM intakes to anyone alos loved the one on my 02 Subaru Wrx." —Warren M from Buckley, WA bought an AEM Short Ram Intake System for a 2001 BMW 3-Series.
