Jim, that's the perfect answer I was looking for! Cheap, simple and precise! Now, let me make sure i have it right. I have some of that insulation at home that has a slit down the side where it would slip over the pipe and I don't believe it's self stick. If I'm remembering correctly, the stuff you're talking about is the same except that the slit has some self adhesive on it so that once it's slipped sideways over the pipe, the seam will stick back together and seal itself off?

Cheap, too. On my 560 SL I bought (from the dealer no less) the official replacement. I've learned a bit since then, and everything else has fed from the same length of foam insulation I bought awhile ago. > If the idea is simply to get some flow, but not full flow air through, The idea was to get air flow, without coupling blower noise through.

Yes. Without that flow in-cabin temperature regulation is largely nonexistent. As you've found. > Is it also sampling outside air?

I believe that's a water drain for the air intake plenum. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
