In defense to AFE they make SEVERAL intakes. So to say they all "lose power" is a little off the wall.
BuraQ found substantial gains at the track and on the dyno using the AFE Stage 2 Elite SI Intake. We've been moving quite a lot of those. It's a great intake cause it's sealed box style and only breathes in cold air, unlike other DCI's.
They also have a cold air intake style which is based off the stage 2 elite si, that is a good performer as well but because of the price tag nobody really has it. We've maybe sold a handful of those.
Thread starter, if you need any help I'm a PM away. Our AFE intakes are priced extremely competitive if not better then the competition too.
