Which Bonnet Vent?

[mikeymikewakey]

I have a custom respray planned for my car and was thinking about sorting a good air field while im at it and fitting a decent sized vent on the opposite side to the original (similar to what the nana used to have when it was red).

Just wondering which style would be better suited for maximum air flow?

Not having the edit button is driving me mad.

I meant air feed, not air field.

Although having an airfield would be nice.
