good question i have always wondered this would also be interested to know the reasoning

Purely cosmetic! I think it looks better so I ditched mine

 

[kaks_EK9Rx]

Purely because of looks i think, no performance gains from it

i would leave it on...spark plugs should heat up and cool down slowly. Leaving the cover on will help it cool down slower.

Other than that, there are no clear advantages on or off.
