Hey guys~ I had some different experiece with removing charcoal filters. I tried this on my cls63 and for some reason I did not notice any power gains. The car feels like it's just reving more at given amount of throttle. The response felt more lazy to me with less grunt. I was actually confused of the outcome because this has been proven for a while to be the easiest way to get more power from our 63 engines. I ended up placing the filter back and it feels more responsive I think. It may be because I kept the stock air filters in there instead of using k&n's or may be the intake system is little different in the 09 cls63 which I doubt. Has anyone had this experiece?

I removed mine and replaced the air filters with VRP filters a few days after I got the car. It's hard to tell if there was any increase at all.
