Are the foam Pieces on the bottom of the intake really nessasary?

Those were there to help keep water from collecting under the intake, the seals on the knock sensors aren't real great at keeping water out of the knock sensor wells and if flooded they can corrode the connectors.........and the next thing you know you've got knock sensor codes popping up. There was a factory bulletin on this a few years ago about making a "dam" around those knock sensor wells with RTV silicone in an effort to keep them dry. We don't get THAT MUCH rain out here do we?? This is one of the reasons that the newest engines are getting relocated knock sensors.
