Never quite satisfied with the fit and finish of the TVT intake tubes, I ordered the OE part for the E-320. I ordered two RH tubes per Dave's thread, as he said this was the best fit when used with 1" PVC spacers.

When I received the tubes, I noticed a screen material at either end of the flex tubing. Anyone care to take a guess as to what the purpose is?

The SLK320 tubes and numerous other Mercedes models have no screens, so this isn't a water evacuation function.

All I can see it doing is allowing engine heat into the tube when the car is not in motion.
