Review on AEM 21-475B Cold Air Intake System in Blue by Rick Marie

Install this on a GT 09 Legacy and the car will come to life. I already had a full turbo rear, but now the turbo can breathe on either side. Tons of turbo spool over 3000 rpm. I doubt there'll be a power or torque increase, but the power comes sooner and feels more accessible. This will fit any 05-09 Gt without an engine gauge after 500 miles. For all, there should be a major upgrade over the stock airbox.
