So I just finished installing my Halltech hybrid intake two nights ago and it's worth every penny. It definitely makes power and unlike previous generation corvettes you can hear a huge difference. It's substantially throatier and you can hear it sucking air. Initially my thought was that it was a little pricey but after seeing the quality and the airbox being true carbon fiber it's definitely a fair price. Jim at Halltech is also extremely helpful with install questions and doesn't make you feel burdensome at all! Very happy customer, thanks Halltech!
