 Pontiac Grand Prix Turbo Hood vents
 
Jeeps are known to run hot, especially when pulling very slowly through big rocks and difficult trails. The engine works very hard during these times with very little airflow through the radiator. A set of jumbo sized Pontiac Grand Prix Turbo hood vents was just the ticket to help keep those underhood temps down, and they add a really cool, unique look to Project DD.
 
We began by measuring from a center point on our hood and drawing out grids for reference points with a grease pencil. This helped us to place the hood vents properly on the hood, once we decided on the optimum position.

We then placed the hood vents on the hood and traced the outline of the vents. This gave us the reference to mark our cut lines.
 
Here's our hood after the cutting is done. We touched up the freshly cut edges with primer to prevent rust.

We opted for this position for several reasons. First, the drivers side vent is directly over the exhaust manifold. This will allow much of the heat generated to escape while at crawling speed. (We're not concerned about high speed cooling) Also, the vents just seemed to look best here.
 
Here's the unfinished vents sitting in place. There are other vents on the market that cost less, but these things are huge!

We scored them at the local Pontiac dealer. They fit an early 90's model Pontiac Turbo Grand Prix.

The louvers come unfinished. They can be painted to match the body color, or in our case, we sent them over to Shawn at Arma-Coatings to be sprayed to match our grill.
 
Below is the finished install. The louvers have been Arma-Coated black to match our grill. We installed the vents with a black professional polyurethane adhesive/sealer from Fusor. The finished result is very functional and looks great!
