I was trying to get the serial number on my ECM today and took some pictures, what's that hole that goes nowhere for? The chamer is shaped weird on the top and the inside is empty, looks pretty useless to me.

Increasing the volume of air.. and having a dead air area cushion the pulses created within the intake manifold. (intake valves opening and closing)

This thing is typically called a "zip tube" here in the OEM realm. And that's all it really does.

Generally I like to hear the induction noises. But.. these cars are not really hot rods and keeping it quiet is preferable.

Besides.. nitrous is much sneaky-er and quiet. :thumbsup:
