Hi. Received my cold air box from More Performance. It took about 15 minuntes to put on. The box has one bolt to hold it on and they did a real nice job to make it fit in a tight location. I started the car and left it run about 10 minuntes, then went for the test. I really like the new sound of the engine, about the same at idle but when you stand on it, it really sounds good. It can breath. I can tell a big differance in the way it pulls going through the gears. I would say it was well worth the money for me. Now I can't wait to get my new CORSA exhaust. Thanks Mike and Amber at More Performance.:bouncy:
