If the hole isn't blocked off it should be to stop the cooling air from escaping to the engine compartment instead of going past the cylinders.

This hole doesn't enter the cooling air section of the tin. It just passes from the bottom to the top. So, plugging it will stop hot air from travelling up from underneath, but I'd hardly be concerned with that amount of air. Leaving it open shouldn't affect anything. |

Considering it’s right above the exhaust system, I would close it off so you don’t suck hot air from below. The rubber seal around the engine tin is not for looks, it has an engineered purpose. |
