intake foam?

I think they keep debris out, but I removed them so I could hose out under the intake when I clean my engine. And I figured removing them could help with circulation to keep the intake manifold cool, whereas the foam could contain heat from engine and heat the bottom of the intake. Haven't had them for 4+ years and no issues.

No, the intent was to keep dirt and water away from the knock sensors. It failed miserably though as it also kept dirt and leaves and water ON the knock sensors.
