Not sure about the A/F one intake. I just thought the "box" was there for reason, so I cut the top hose out where it went, and re-installed it. I used a clamp on every junction between the intake tube and the TB to make sure it was well sealed. I'm no expert, but it seems like unhindered airflow between the intake tube and the TB elbow is what causes the noise. The "box" sort of acts as a "muffler".,,,,98
