Well, my experience has shown that not to be the case. I've driven and seen others drive around with astoundingly little air seal rubber on hot days with no overheating. The fresh air scoops force in so much air that those small gaps in the rubber would let in a negligable amount of hot air, especially at highway speeds. Of course, Gene Berg experimented and found that even opening the vent windows on his splittie would change the air flow to the air vents and effect the cylinder/head temps. Of course the best way to find out is to glue or at least temporarily seal the gaps and see if that solves the problem. If it does...great. But, if as I suspect, it doesn't it's time to look elsewhere. But let me be clear, there should be NO air gaps in the engine seal, it can't be good for the cooling process. I just have my doubts about whether that is really the root cause of the overheating. James
