"Bought this for my 03 WRX, Now I already know that an Intake on these cars doesn't improve much of anything but the main reason I bought it was for the sound. While the short ram technically doesn't require a tune, I would still reccomend it. Aside from that it sounds awesome, really brings out the stock BOV also. Makes the exhaust a little more throaty as well. Overall very satisfied with my purchase and can't beat the price!" —Michael R from Tyngsboro, MA bought an AEM Short Ram Intake System for a 2003 Subaru Impreza, WRX, 2.0L 4 cyl. engine.
