When removed, it does seem to lower under hood temp (important for the short ram intake crowd) and does appear to help 'a little'. I have done this for a month (July/August in DC) and seen a consistant slight but noticable difference in acceleration - enough that i would do it again. The heat gets to rise up/out of the bay instead of being forced down under the car.

The downside is that the engine is a little louder - most noticable above 80 MPH (30,000 cm/hour for the metric crowd ;) ) The noise doesn't bother me - again, the trade for a little more performance is worth it.

And if you are careful taking it off - you can always put it back on.
