If you are the DIY type you can get some mess grill from home depot and
attach it by yourself. There are a lot of websites out there describing the
procedure and if done correctly it looks same as the ones you purchase.

As far as air flow goes, on my 98 accord there are two openings--top and
bottom. If I were to put grilled mesh I'd put it on the bottom and leave the
top open. Actually the top is slightly covered with the front bumper sticks
that go across horizontally. They are also bent slightly to bring the air to
the top of the hood straight into the engine compartment area thus allowing
to cool the engine in addition to the radiator and fans.
