I have a '91 Camaro 3.1 V6. The grill is from an IROC with the places for fog lights. I don't have any installed there and was wanting to run ducts from there to the snorkel. I heard doing this procedure caused slightly more temperature increase for the engine and radiator because of the air flow\circulation is reduced due to the vents coming up from the fog light area is going to be between the engine and cooling fan. Any comments...please help.

I have heard the same thing . I have just the bottem of my boxes slashed and I have the grill that looks kinda like mini blinds and they are tilting downward . I think this grill kinda pushes the air up . If your car just came with that grill like that , maybe you want to look at the type of grill I have . Just something to think about .I've been working on getting my digital camera as soon as I get it working , I will snap some pics for ya .

 

Yes its true the engine may run a couple Degrees hotter, if your really worried about it get a 180 thermostat. Thats the lowest I recomend going for the Comp/lack of heat and defroster probs.
