Intake Screen Removal: Any Gains To Be Had?
I have noticed that the M272 3.5L motor has two screens on the intake tract. Now I agree that screens on the intake work to smooth out the intake flow of air for more accurate MAF readings and help accelerate the charge for better cylinder filling (which are very good things), but two screens back-to-back seems excessive. There is one on the upper plenum side and another 4" away on the mouth of the MAF sensor on the manifold side. Has anyone found any gains removing one? I would guess the one on the upper intake plenum side is superfluous if any.

You're not smarter than Mercedes engineers, I'm not smarter than Mercedes engineers, no one who ever has or ever will post on this forum is smarter than Mercedes engineers.
The smart thing is to leave it alone.

So again, any heard of getting any gains from an aggressive "screen reduction" program?

That aside, Mercedes has not been a very smart company in the last 15 years. Their reputation has been badly tarnished by poor engineering, inappropriate materials selection, sloppy manufacturing workmanship and a corporate structure more interested in the Deutsche Mark than engineering excellence.
Now if you’re talking about pre 80’s Mercedes (any model, in my opinion), then you and I are in full agreement. Outstanding engineering that is top of class and built to last. But modern-day MB’s could use a little improvement. Why there are two screens on the engine, I have no idea. Perhaps someone on this forum, or other forums, might know. Then the question would be answered.
Finally, if the guy wants to risk his own car in the pursuit of, perhaps, making an improvement, what’s it to you? It’s not your car he’s tinkering with.
