I removed this baffle out of the can that the air intake connects to right before the turbo. Wondered if it was just a baffle to cut down the noises from the turbo, or had a performance purpose. Turns out it has no effect on turbo noises, and I could feel a real power loss in the pedal. After looking at the whole setup closer, this unit is more of a funnel into the turbo than it is a baffle. I put it back in and definitely felt the power return. Just a friendly FYI.
