Wind Vibration on 1997 E420

After having the oil changed on my 1997 E420 at about 65,000 miles, a wind noise started up at about 60-65 mph. The vibration is in the front pillar on the passenger side. It was really loud and at first I thought it was the moulding that goes down the rain channel, but that didn't seem to work.

The next time I changed the oil at about 70,000 miles the noise changed to be less noisy, but it still is quite prominent.

Could there be something in the air filter induction componants that are removed for an oil change that could be causing this in the pillar between the windshield and front passenger door?

Thanks for any suggestions or help.
