Is the cooling ducting needed on the '85 TA? I have that black spoiler (its pretty beat up though). I saw sometheing on it in High Performance Pontiac in the new issue. Any body know where I can get one? My car runs a little warm (around 220) but I also have a coolant leak.

 

The air dams you'd get from a junkyard will probably also be beat up. They're not expensive, about $25 I hear when bought new. Ideally, the air dam should be angled a little bit forward so it scoops up air and directs it through the radiator. If it's angled backwards, not as much air will go through the radiator.

 

Thanks for the help.
