Has anyone done this? I'm in the process of replacing my lower intake manifold (!!!) and while I'm in there I figured I'd look at polishing up the manifold to maybe increase air flow.
Some argue the rough surface helps to break up the air molecules, while others say a smoother surface allows for greater airflow due to less friction.
Thoughts?
