How to:</font> With the hood closed, take a pencil and trace out the shape on the hood. I went back over it with a straight edge.</font> Open hood and decide whether to cut one big hole on the backside or three like I did.</font> Cover front of car with fender guards, because you don't want to rub up against metal shavings against you paint. Cover entire engine.</font> Remove the Hood latch
Time to cut. smile.gif</font> I used a pneumatic grinder with metal cutting disc. Slowly cut along the outline, making deeper passes each time. Take a break to let the disc cool, so it cuts better. I had a friend hold the hood down to a comfortable level.

For the back I removed my whole air box assembly and sat on the cross member while someone pulled the hood down on me. It made it easier but isn't necessary.

For some areas, I had to get a smaller diameter disc to get in the hard to reach areas.</font> Reassemble like above</font>
I used a black duct tape like tape to temporarily clean up the cuts, but I am still looking for something else that will look more OEM. Like maybe a rubber seal, or something.

Only took me 2 hours, including air box lift.

I saw a how to a couple years ago, and then during auto shop, I took the grinder to my hood. I made it into a ram air-like hood. I know it is a minimal or no real ram, but there is a definite increase on acceleration above 50MPH. I'm sure I increased the cold air in the engine compartment. I also raised the air-box.With the hood closed, I can actually see most of the air filter.

Some other members have done the same and even added their own special touches.

clean2000birdv6 Added a screen and painted it as well for a cleaner OEM look.

Pros
</font> Almost FREE, depending on your tool resources</font> More ambient airflow into air box,Same "ram" air effect as th "Ram Air Hood"</font> Distinguished SOTP feel when pulling after 50MPH</font>Cons
</font> May look like a "ghetto" mod, if done sloppy</font> Engine bay gets dirtier quicker</font> May be dangerous to you and your hood if you make a mistake.</font>
