I removed this foam under the intake tube when I pulled the baffle out from the intake. Is this just sound deadening or is this for heat sink for the EGR cooler?

My understanding being both but mostly sound. I removed both long ago and never put the plastic engine cover back on to allow better heat release. I do live in Florida so many not If in a very cold place.

Thank you, I saw an old thread off of this forum but I couldn't see the pictures since it was so old. I figured as much. I didn't notice a difference in sound either way =/
