Lower Engine Panel Removal Opinions?

[CCCLXXZ]

I performed my first oil change last night and after removing the lower panel, I had some consideration to leave it off. I can understand the engineering perspective to use a panel to shield the engine compartment and improve on aerodynamic properties. My logic behind keeping the panel off would be to increase heat dissipation from the engine bay by allowing air to travel through the front of the vehicle and flow out under the engine and exit through the underside.

At this time I am not using the vehicle for tracking purposes and don't feel like it is a particular benefit beside providing some additional protection. It seems as auto manufacturing develops, companies are choosing to use more plastic to cover components both in the engine bay and under the chassis to isolate different components.

Has anyone opted to keep the panel off? Please post your opinions...

Thanks,
