There are a couple folks here that have put on hood scoops or vents. Most of these were not stick-on varieties, but rather taken from other vehicles and melded to fit the Bonne hood for a new look.
In some cases, at least two that I know of here, vents were put in not only for looks, but to help cool of some pretty good performance modded engines.
I think there was also a memer who used scoops from a trans am.
These aren't everybody'* choice, but they are options to consider for changing the look.
Do a search or two and see.
Also, to add to what some others have mentioned, take a look up top in TECHINFO and read up on the first performance mods we recommend. Many can be done for little cost and just some time and effort on your part.
