None.
With M-B's there have been lots of talk about K&N's actually hurting performance, and not functioning as proper as the OEM Filters. M-B's OEM Filter's are perfect for the job. Also there have been people that said the oil has screwed up their MAF's, I never had that problem on all my previous cars with a K&N though.

Yup. 
You'll find that it's not easy (or cheap) to unlock HP on an N/A M-B motor, aside from some CPU stuff, bolt-ons are very few and far between, and/or not helpful at all.

Its very simple there will be no noticable gains in performance and it will create the possibility of damage plus the additional noise. They are a bad investment fraught with risks.

This debate has been ongoing for 20+ years.. K&N's are not risky... They have been run on millions of cars and allow considerable more air flow than a cheaply crafted paper filter. The worst case scenario is that "oil" gets on the MAF.. which I've seen a ton of dirty MAFS on cars that ran stock filters .. easy fix - alcohol on a Qtip.. better air flow and reusable - don't have to buy new filters every 3k - 9K miles.. personally I like AFE's but same animal..

It may flow a tiny bit more, but it also lets more dirt through. Cars with K&N filters almost always show higher silica in their used oil analysis. You want to accept that for zero performance gain? why?

With a 20HP gain which you will not get with such snake oil as a K and N you may see an .01 sec difference in 0 to 60 times. You will also not see any noticable or significant gains even if you put it on a dyno. Ain't worth the dollars or the potentential grief.

20 HP is a pipe dream with a K&N.
If gains are anything, you're looking at less than 1HP for an N/A car. With M-B already using hi-flow Air Filters, I wouldn't be surprised if even a loss is possible.
