Yeah too much foam increases your engine bay temps. I'm planning to remove some too. My intake temps can hit 190F! But it helps lower the coolant temps. That's why I did it. I'm sure you saw a drop too.

Yes but what has all the extra foam done to your under-hood temperatures? How much foam was there from the factory? I recently installed an Koyo HH-series radiator, and I added foam to the sides of the radiator where previously there was none. I am now seeing 5 deg F higher intake air temperatures on average when moving, and when stuck in traffic the heat soak seems more rapid, with intake air temperatures higher than I had seen before. After half an hour in traffic, not moving, in 100F heat, I was looking at the following situation: A/C off, fans on, intake air temperature of 170F, coolant temperature of 190F. The intake temperature had climbed until it stabilized at 170F, and at that point the fans stayed on constantly irrespective of coolant temps dropping below the fan activiation set-point. Incidentally, it looks like my ageing battery kicked the bucket recently, and I wonder if it had to do with the extreme heat soak.
Now, I could have something weird going on, like only 1 fan working and 1 not working, but barring that, I plan on removing some foam from the passenger side of the radiator.
