On my E200K the cold air intake pipe is missing, what are people’s opinion on its impact on fuel economy with it not being there, and or performance
 
You need a cold air intake. Cold air is denser than warm so, when mixed with fuel and ignited, you get a bigger bang for your buck.
That's why a cool dawn drive is so rewarding.

Teego has summed it up perfectly. You'll definitely be missing out on a bit of power, especially as things heat up in the engine bay.

The difference in my car of the hot summer air (25c+) and the frosty cool winter air is fairly pronounced, I don't have a rolling road graph to back this up, but even if you ghetto rigged some flexible pipe to give it a cold air feed you'd notice a difference (though I don't recommend this) as Mercedes boffins have designed the cold air intakes with some thought in place.

When servicing my Golf a couple of weeks back, in haste I left a piece on the air intake off as I didn't clip it back in properly, so it was sucking in hot air from the engine bay, I went for a drive and instantly felt a difference...reduced power and MPGs were not as high as before...
