Is it polished or chromed? The entire plenum or just the top?

...that's an interesting thought, if the inside of the plenum were polished, would that affect performance?

If you make it too smooth it will HURT performance slightly. It all has to do with there needing to be surface roughness for air to get trapped in, so that the air moving beside it can flow freely. If the surface is too smooth, friction and turbulance becomes a problem.

That's an over simplified explaination but hopefully you all get the point.
