To give the front of the Prelude a more aggressive look, I decided to cut some large holes out of the hood, which will also serve as air outlets. To not make it look crappy, it's important that the holes on the left and on the right are symmetrical. So for marking the holes, I used a mold.

With a jigsaw I roughly cut out the holes. To make sure I cut straight, I used a straight piece of wood. I secured the wood to the hood using clamps.

I ground away the corners with a Dremel tool, because that's far more accurate than the jigsaw. I filed off all flash, and finally I sanded all the edges to a smooth, even finish.

As you can see, I followed the inner structure of the hood. That way, you won't have to cut through the reinforcements of the hood.

For the finishing touch, I chose to go with fine black mesh, so with small openings in them. The mesh is secured on the inside of the hood and clamped between two layers of metal. The edges will be kitted as well.

This is what the result looks like seen from above. Underneath there are a number of photos from different angles.
